yea man buy an old car and riddle it with fancy features: (TPMS):tire monitoring pressure system, Lidar for brake anticipation and also highway cruising, parking sensors and cameras back and front, dashcams front and back (even cameras at the door handles like a Tesla). Tbh i like it when an old car gets modded by third party with latest car features that way u really saving the environment from a ton of metal junk. A BMW or A Tesla are just filled to the brim with sensors, but also more parts mean more breaking parts so there should be a balance between refurbishing an old car and making it basically undriveable with breakdowns.
