Oh good, maybe this is the version that gets all the vehicle types read for 14.2!

I'm hoping that this is the version that really smooths things out. Especially now that they have more data from the fleet.

Ok so I have the new update in my 2023 XLR
14.1.4 big changes so I am ok with some im not so sure about other things.
So first no more setting speed . You now have pre made profiles from Chill to mad max. Each has a pre made speed and driving style.
Overall better than before.
BUT
divided highway with a guard rail between the lanes ....
If an ambulance is going the other way the car puts on directional and pulls over and slows down.
I have found it trying to slow down when leafs blow in front of the car.
I have had to grab the wheel a few times when it does a quick turn like it's trying to dodge something.
So yes it works ok but something is up with it.
WARNING
In MA on the news they showed a Tesla drive by a school bus with lights flashing, the drive was stopped and said the car was driving. So the next day I saw a school bus with lights flashing in front of me so I tried my car. Yes I had to stop the car it would have drove by the bus.

The 14.1.5 build is only for the Cyber Truck right now. From what Chuck Cook has seen (he has videos on YouTube) that jittery behavior is better. Not the best at parking yet, and in Florida where he is there aren’t leafs to test the truck’s reaction . Looks like a good build, hope it addresses the driving around leaf piles issues Too.
