So I've had 2 model 3's now over 4 years, both with USS, and had FSD on the first one, EAP on the second.Thanks GRiLLA, good point, it's certainly a risk I need to weigh up.
The issue appears to be that Tesla remove the facilities before they have replacements for them. I'm aware of things like Autopark and Summon for example, as well as the parking issue using Tesla Vision.
Whilst I realise that Tesla have moved to Tesla vision for FSD, it appears they neglected the need to still provide decent parking details.
As has been mentioned, FSD and to a great extent EAP are useless on UK roads, particularly in it's current state. It's such a shame that something as simple and necessary as decent parking sensors have been neglected.
AutoPark and summon are gimmicks, it's occasionally entertaining to use them but they really aren't useful as everyday type things. I would suggest that most people on here feel the same. Unessential gimmicks.
AutoPilot however is something that I use routinely on motorways. Using it anywhere else is far too terrifying for me. I wouldn't be without the lane change feature either, the complete experience transforms long journeys like the trip I recently had Oxford - Kintyre, used AP the entire motorway route with no issue. If you read the threads on here it's a topic of great debate, some people find it unusable, other like me find it amazingly valuable. I try to avoid getting into debates around it as nothing good ever comes of them as people get very animated around their safe or not opinions.
I don't park in a garage, but reverse around another car to get onto our drive, I don't find the USS especially useful as like others have sent they just say Stop far too soon. If you only have a few inches around the car in your garage you are likely to find the same. I don't think this is really a Tesla things as my previous cars were no better, just starting panic beeping. The cameras are excellent for reversing, less so for going forward, these days I reverse into any spot. I see the only value of USS to be highlighting something I might not have noticed.
I've not tried the USS-less cars yet so have no valid experience, but I like the way they seem to highlight kerbs which is harder to judge in my car.
