I read this article this morning and it seems a bit worrying. New tests of automatic braking systems found a worrying flaw — and 2 Tesla models did the worst "The IIHS said the Tesla Model 3 and Model S were the only two that didn't stop in time and that hit the object." They also noted that the Model 3 brakes way to often for no reason....I agree! "The IIHS said it also found the Model 3 was prone to "unnecessary or overly cautious braking." "While traveling a distance of 180 miles, the car unexpectedly slowed down 12 times — seven times after spotting tree shadows on the road and the others after detecting vehicles traveling toward it in another lane or crossing the road far ahead, the institute said." I agree 100% with this statement and I experience it daily in the Model 3... the Model S i'm driving now ( model 3 in the shop) is significantly better at braking when needed. Model 3 makes me car sick in traffic and tends to upset drivers behind me who think i'm brake checking them... Hopefully Elon addresses this issue asap and releases a OTA fix!
