Been running FSD with v14 lite on my 2019 M3 (HW3) for a couple days now and honestly I feel pretty disappointed so far. It feels like a step backward for me in a lot of ways.
It's just not as smooth. Following distance handling feels jerky, and phantom braking is happening more often now, though the good news is it's not nearly as hard as it used to be. Little taps instead of slam-on-the-brakes.
It's also slow. Like painfully slow at stop signs. It sits there way longer than the old version did, long enough that I start feeling awkward about the car behind me. Lane keeping is a bit more jerky too.
The one thing I do like is highway following. When the car in front slows down, it reacts right away instead of lagging behind. That's a real improvement.
Overall it kind of feels like it might be driving more safely, which is good but it doesn't feel as confident to me. It's definitely not a better driving experience. Just overall less pleasant to ride in.
Hoping some updates smooth it out. Post your anecdotal reviews below. #cars source
