Tesla Safety???

In 2021, Tesla engineers tried to convince Musk not to give up on radar for its Autopilot and Full Self-Driving effort. The automaker decided to remove its front-facing radar and ultrasonic sensors. An approach called "Tesla Vision ” where the automaker believed that the best way to achieve self-driving is through cameras. 

Some Tesla engineers were aghast. Without radar, Teslas would be susceptible to basic perception errors if the cameras were obscured by raindrops or bright sunlight, problems that could lead to crashes.

Musk was unconvinced and overruled his engineers. Soon after, the company began disabling radar and the result was an uptick in crashes, near misses and other embarrassing mistakes by Teslas without the critical sensors.

Later, Tesla introduced a new radar sensor, a better version of the previous radar, but not by much. Given its narrow field of view and it's placement behind the bumpers as before, the new radar can better detect objects in front of the car, but it has no idea whether the car's path intersects with the objects, or if the road takes a turn before that.
