Headline claim only pertains to rear end collisions (which to be fair, are a large portion of collisions on our modern cell-phone filled roads). AEB won't save

Headline claim only pertains to rear end collisions (which to be fair, are a large portion of collisions on our modern cell-phone filled roads). AEB won't save you from losing your shit in the woods trying to dodge that deer or road debris you couldn't see until last minute nor will it save you from entering a corner too hot.

True, but the latest generation of electronic stability control systems with brake-based torque vectoring are pretty good at handling those situations. Many cars already include that feature and it will probably be universal in a few years. https://www.motorbiscuit.com/do-you-know-what-torque-vectoring-in-a-car-is/ https://www.motorbiscuit.com/do-you-know-what-torque-vectori...

  Nothing will save you from physics. The tires can only apply so much force to the vehicle in order to change direction or speed. A stability control system fundamentally trades distance traveled forward in exchange for not getting sideways. ESC is good at preventing people who don't know how hard their vehicle can actually turn from going "all in" with the brakes and winding up off the road because they robbed the car of all the tractive force it was using to turn. For example, if you whip around a turn at a high rate of speed and there's a deer there ESC will keep you on the road, you're still gonna hit the deer though. I think all these technologies are beneficial because they bridge the gap between the hapless dolt and the driver who can get the most out of their vehicle but no amount of breathless hand wringing and low effort internet comments will ever change the rules of physics.

    I think you missed the point. Adding brake-based torque vectoring to ESC does more for crash avoidance than just ESC alone. It allows the vehicle to rotate faster by maximizing use of the available traction at all four wheels. Even drivers who know how to get the most out of their vehicles aren't able to selectively brake the inside wheels while turning. This isn't magic and won't prevent all crashes, but will prevent some.
