For almost three years I drove an S90D. It had the original AP with the MobilEye hardware and software. We did a number of long trips in the car (> 1,000 miles) and the AP was very good. Not perfect, but very good and very smooth on the freeway.
A year later in the spring of 2017 Elon touted the new Tesla proprietary AP as "smooth as silk" and I felt kind of jealous with my "old" 2016 S90D.
Last December Tesla rang and offered me a demonstrator S100D. Same color, sunroof, wheels, interior and monthly payment and they would forget the fees and remaining payments on my current lease. Hey, why not? They were trying to convert inventory to cash and it worked for me.
So now I'm driving a 2018 S100D with the "enhanced" autopilot which as far as I can tell means 5 cameras, plus radar and the ultrasonic sensors. The AP is NOT "silky smooth"!
Cruise control is set to "4" and "avoid frontal collisions" is set to "medium".
- The cruise control "surges" when following traffic, about as badly as my BMW i3; which is pretty bad! It over compensates, slowing down too much, then accelerating too hard, slowing down too much; repeat until annoyed and switch to manual.
- The car abruptly slows if a car in an adjacent lane comes anywhere near the lane line; just the usual sort of slight wander that is unfortunately common on California freeways. Then the AP thinks about it for a second, concludes the car isn't coming into my lane and accelerates.
- When changing lanes to pass it will absolutely not accelerate until the lane change is completed and there is no traffic ahead.
- The AP tends to float to the outside of the turn on the freeway before pulling itself back to the middle.
- Today, taking a sweeping right hand turn at 70mph, which was bounded by a 4' cement median well away from the left side of the lane, the car abruptly slowed and accelerated four times, like it was treating the corner as a series of straight lines. Literally four years ago my wife was in the car on a test drive going around this corner at 75 on AP and it was very smooth, eventually leading us to buy the 2016.
So do I have a lemon? Do my cameras need adjustment? Is the Tesla AP, with more cameras and a faster processor, simply worse than the Mobileye AP?
