**** If you could specify what you are driving, when you got it and if you know if it has radar or not would be helpful in this thread. ****
Pre-rant disclaimer. The money savings alone going to and from work make me put up with more than I would otherwise. If I could find something about the same price, with similar performance, at least the range of the M3LR and that was from another established automaker I would consider jumping ship. That sentiment comes from nothing other than the fact that the car doesn't actually have a functioning cruise control.
I can't speak to FSD as I didn't buy it. However I put 900km (560 miles) per week, everything from urban to county to highway and use Autopilot a lot.
I'm driving a 2022 M3LR that was delivered December 21, 2021.
Just so there is no misunderstanding.
- Highway - 3-4 lanes each way, divided with barrier, flow of traffic is usually about 120km/hr
- County - 2 lanes each way, no division other than a painted line, flow of traffic is usually about 90km/hr to 100km/hr, pretty much flat with some curves
- I am referring to TACC and not auto-pilot, though the behaviour is the same.
- I only use it on clear roads
I've had a few phantom braking instances on the highway, but I think it is actually been better because I am usually driving at night with no shadows this time of year, we'll see what happens when we get closer to the summer and the sun is breaking the horizon at 6:30 AM.
In the county TACC is absolutely useless during the day and worse at night. I get phantom braking all the time. This happens when it's on flat level ground with no curves. I haven't made it though a drive to/from work with out it engaging at least a few times in the county.
- Car coming towards me with it's lights on, car freaks out
- Bus/Truck coming towards me with.....oh no..... a shadow, car freaks out
I'm not talking about the car slowing but rather it's jamming the brakes on, after yesterday's drive with my wife, I am now also in the no TACC while she's in the car club.
I have a friend with an older M3 with radar and has zero issues on the same county roads, he was surprised when I mentioned it.
My firm belief is that Tesla screwed up by removing the radar pod. (I still think it was a cost saving measure, remove a part don't change the price of the car).
I drove a 2016 VW Golf R for 5 years prior to buying my M3, it had adaptive cruise control which is very similar to Tesla's TACC. The only time I had the car engage the brakes was when I nearly rear ended some one, as it should've.
It baffles me that there has been no response from Tesla on this issue, there is no way that it is unique to a few cars. Unfortunately it'll take a pile up that happens because of a phantom braking incident for them to take notice.
Autopilot was designed to be used on four lane roads (two each way), NOT on two lane ones. If you're going to mis-use the car, quit complaining. Or learn to drive it correctly. YOU ARE THE REASON folks want to throw up while riding with you. It's not an awful awful car, but you are likely an awful awful driver.
Interestingly, though, my 3 does not freak out when I drive with AP on while driving on a two lane road. You probably forgot to tell us of the hills and curves on your road (that you're calling a highway). When you crash, I'm sure you'll try to blame the car, but I imagine you won't be able to. And, it will likely be your fault.
You're gonna need to cite that for me, what do you mean not designed for two lane highways. My old Golf and my wife's Atlas both have adaptive cruise, again with a radar pod and drive just fine on two lane highways.
I also suspect that judging from your signature you drive an older M3 with radar. This furthers my belief that not having it is the source of the problems we are experiencing.
