If the most advanced semi-autonomous car on the market today is getting a C, who's getting the A? Lol.

As I understood Tesla to say, this is still beta, hands on the wheel, eyes on the road. Things are not guaranteed to work. And still it's the best out there.
Sounds to me like it is doing what it was supposed to, and yet we continue to get upgrades, and it improves. Tesla also says that it "learns", which I can vouch for in several instances. Maybe where you live there is not enough data being uploaded. ??

And where I am it drops you at the road entrance to the parking lot (if you're lucky)and says "drive to supercharger"
I recently took a 1500mile trip with the family for the first time in our new 70D and my wife asked me a few times why they don't put up a single sign with an arrow telling me here the damn chargers are....Some of the SCs in northern Virginia are located at huge malls and it isn't always obvious where to go. I never had a decent answer for her as I sorta had to agree...Navigation improvements would be nice but as a software engineer part of me wonders if maybe we could fix this problem with the simple low tech solution...
The C grade is based primarily on Nav and that a high school kid has built a better and more accurate Nav planning tool than Tesla has yet been able to produce.

Agree. Wonder if we need to be careful before his ego gets too big for his britches though

This has been a minor problem since day 1. I don't think Tesla can do anything about it, you just have to use your head. Remember paper maps?
I e-mailed my sales rep, Michelle Chang, about this extremely dangerous behavior a couple months ago - and said this is gonna get somebody killed. I gave her the exact highway and stretch of road where this diving-into-oncoming-traffic behavior over hill crests happens (highway 395 between highway 14 and I-15 in California). She claimed she would forward the message to engineering. But according to this discussion the behavior hasn't been fixed yet.
I have *not* driven that stretch again myself since 7.1 was released so I can't speak from experience. When my car gets here in April I'll test it again and report back - the autopilot Tesla I experienced the behavior with was a 7.0 70D rental.

Google maps often goes inside buildings, like malls, and even bars around here. Tesla has only a limited number of superchargers, it shouldn't take much time to make sure they are all updated and accessible on the map.
It all comes down to the same thing. They've spent all this engineering effort on the fundamentals but almost no work on the user interface side since this original design. Guess what, that's what all the people buying the cars experience.

haha. Sorry for your loss. It really is just a gimmick at this point, but I feel your pain. It's a fun gimmick.I gave 7.1 an incomplete, due to lack of summon.
Hopefully it will get there soon. Have you asked your SvC as to why it's absent in Canada?
To add a point to Tesla/Google's inaccuracy with regard to superchargers. For the Tesla Supercharger in Tifton, GA Tesla Nav directs you on to the entrance ramp for I-75 South. Would they put a SC on an entrance ramp? I know of two park & ride lots with Level 2 chargers that you enter from a freeway ramp so it wouldn't be too unexpected. Elsewhere I've seen other roads split off from entrance ramps. Fortunately I was dubious and drove around in some industrial access roads and parking lots to find the charger behind a Starbucks and next to the entrance ramp. In this case though it seemed that Tesla/Google have the SC located properly and accurately on the map with Lat/Long (unlike some malls where it is located in the middle of the interior food court) but Nav needs to know that it is NOT accessed via the entrance ramp (which would add an additional 13 miles of driving.
Oh, and thinking about Tifton GA. We'd headed there from Auburn AL (War Eagle!). Interestingly, Tesla Nav, instead of sending us directly from Auburn to Tifton (a 162 mile drive with 242 miles of range available) wanted to send us to Macon GA and then to Tifton — an extra 90 miles of driving. EVTripPlanner sent us direct with an estimate of 168 rated miles used. We arrived having used 162 miles of range. EVTripPlanner 1, Tesla 0.

One thing to keep in mind for everyone, the nav screen on the instrument cluster is run by an on-board Navigon/Garmin database. The main screen is Google maps. When you tell the car to nav you somewhere, the main screen looks up the street address of the destinatino and then sends that street address to the on-board database and the turn-by-turn goes off of that. So in that case the turn-by-turn will only get you to the street address (so for a mall it will be the main entrance). However, you should be able to zoom in on the main screen and using the map itself you should be able to drive to the SC location. Hopefully I didn't confuse everyone more...

I drove 900 miles from Boulder to Dallas on 7.0, upgraded in Dallas, then drove 1,200 miles around Dallas and then on to Pagosa Springs on 7.1, so I had a pretty good chance to compare. Here are my comments.
The actual Supercharger locations are very accurate. The problem is the turn by turn instructions are done by the on-board Garmin GPS, not the main screen Google/Tesla map. What I do that is pretty simple, when I am close to the Supercharger (in the parking lot), is zoom the center console map in all the way and turn on Sat mode. This gives you a good aerial view of the area with your location and the Supercharger both on the screen. If you put the map in "route up," then you can get oriented very quickly and find the chargers.
My biggest complaint in this area is when the autopilot would occasionally mistake a vehicle in the adjacent lane for one in front of me, and start slowing very quickly. It does not happen often, but when it does, it is shocking and can be dangerous if someone is close behind you.
I saw this behavior as well, trying to switch lanes to the left. After it happened a few times, I noticed that it was 100% correlated with the auto-pilot not recognizing, nor depicting that there was a lane to the left to move to. I assume that the auto-pilot will not move you to a lane that it cannot see. I accept this as a safety issue. My solution is to just move manually to the left (the turn signal is already on), and then when the auto-pilot sees the new lane, then re-enable lane keeping.
Here are a few other issues that I noticed:
When taking a turn, the lane keeping often falls behind, and drifts to the outside of the turn. It even depicts that this is happening; what I see is that when it sees the problem, it does not fix it; it just stays on the outside. When I try a gentle push to help center the car in the lane, it just gives control back to me.
In the 6.x versions, the Energy:Trip screen worked very well. It seemed to average the last 10-20 miles against its internal model and then extrapolate that usage to the end of the trip. 7.1 seems to use a very short average, that has a lot of noise. At first I thought that the predictions were going spastic, with the prediction for SoC at the end of the trip jumping as much as 6% of charge. When you are expecting to arrive at the next Supercharger with 14%, having that suddenly drop to 8% can be quite disturbing. After a while, I started seeing that these jumps were correlated with short-term bursts of power usage, or lack thereof. I really liked the 10-20 mile average. This short-term baseline for the end of trip prediction makes it much less useful.
The undivided highway restriction of Speed Limit + 5 mph is horrible. On a lot of remote roads that I drive in SW Colorado, that is a real pain. I have tried keeping lane-keeping on and using my right foot to maintain speed, and also just using TACC speed control with me steering. Steering is much easier than speed control... Below are a couple examples on today's drive from Santa Fe, NM to Pagosa Springs, CO.
US-84, north of Española, NM. Looks divided to me...
US-84, north of Abiquiu Reservoir. Not divided, but this is the kind of open, highway that lane keeping should do well on...
