Highway driving is different than local driving as it’s easier to quickly assess obstacles, dangerous situations, etc.
it’s possible the car can see more than the driver can at a crowded intersection, thus it’s possible the emergency braking can react and prevent an accident before driver can notice the situation.
on the other hand, an alert driver following one or two vehicles, or driving without any cars ahead on highway can easily determine if the phantom braking is warranted, or faulty.
I’d never suggest automatic pulsing of accelerator to override every time the car brakes suddenly, but if there’s nothing in front of car for ¼ mile, odds are the system reacted to something that wasn’t a threat. Further, an alert driver, aware of vehicles behind them, can easily judge whether the risk of braking in front of a tailgater is greater than the risk of braking for no apparent reason. If driver is following a pack of vehicles, they might determine that the car senses something and trust the system.
Phantom braking isn’t 60-0 instantly. The car doesn’t lock wheels and skid. There’s sufficient time during the braking event for driver to assess the situation. I’ve had car three months and had about 10-15 braking situations I didn’t feel warranted (nothing in front on highway). In every situation I was able to override before car was travel speed dropped ~5 MPH
It’s not a big deal as long as driver is paying attention. If not paying attention car will continue to slow, eventually creating a dangerous highway situation.
autonomous vehicles aren’t perfect. They don’t have to be, they just have to be better than humans. Understanding that, driving is a responsibility.
eyes on road, hands on wheel, foot on accelerator, check your mirrors, and you should be okay
if it’s a problem, you should report it. Take dash cam, then press scroll wheel and say “bug report phantom braking”. Set a service appointment, when they get in touch with you, email the cam footage. they’ll follow up with a diagnosis, and alert engineers. Complaining in threads doesn’t accomplish anything. If it’s an issue, report it
