i know there has been a lot of discussion on this but i didn't see anything quite like my feedback, so i figure i will post. i just purchased it as an add on and after a bit of testing, I am thinking i will return it and ask for a refund. below is why, please tell me why i am wrong. thanks!
autosteer - i tried it on a very curvy highway with speed limit 55 and it worked well but i am looking over at the giant SUV in the lane next to me and i am wondering how much reaction time i have if the EAP effs up before i collide. i am thinking it is less than zero. works well 99.9% of the time is an accident in waiting. the use case that most intrigues me is stop and go highway traffic and i trust it to do that much better than i do, but that is hardly worth 4k by itself.
auto lane change - worked well but didn't stress it by requesting a lane change with a car in my blind spot. i am ok assuming that works.
park - worked ok for parallel but in a parking lot with perpendicular spots it never prompted. dunno why; i guess i wasn't positioned exactly right. i can parallel park just fine, where is the value here?
summon - tesla app played sit and spin, waiting to wake up. it is not at all unusual for me that this happens for a min or three but it still works to open the door, unlock the trunk, etc so i never sweated it. if i want to summon the car and i have to wait 5 minutes for the app to wake up then it is sooo much less useful.
it didn't help that on the day that i did this (23 sep 20) the whole tesla network crashed and i had to use my card to get it to let me drive home.
