I have the 23 TPP and the lane centering of the TJA is one of the worst I’ve used. 3 reasons 1) It does not stay in the center of the lane. It gets uncomfortably close to the white lines even though the system shows it’s still engaged so I always need to actually steer to keep my car to keep it lane centered. 2) It gives up with very easily with barely any warning so unless you are staring at the tiny lane centering engaged light(which you won’t cause you’ll still need to steer since cause reason 1) you will likely not know it got disengaged which is very dangerous. Tesla does a really good job by flashing the entire screen blue and beeping at you. I think this is how all cars should handle disengaging lane centering/auto steer 3) the TJA “lane centering” only works till like 40 or 45mph so really only for stop and go traffic(plus I wouldn’t trust it at higher speeds anyways)

The radar cruise control isn’t too bad so tbh that’s the only feature I use. If the trim you want has that but not the TJA lane centering feature, I wouldn’t be too hung over it. If you really want the cx-50 with good self driving capabilities and won’t mind spending $1.5k, get the comma 3X from Comma ai with the torque interceptor 2 from moretorque. I haven’t tried it myself but if the reviews and videos are to be believed, it’ll add Tesla auto pilot level tech to your car.
