No but I'd buy it if emergency-braking-on-imminent-stop-sign-running feature worked to prevent half of run stop signs from being run.
By your logic, AP1 and AP2 are worthless because AEB, lane, holding, collision detection, etc are also not 100%.
This is why this is an assistive feature. It's a backup to the normal device that has primary responsibility to stop at stop signs. As far as the car actually starting when told to, it's the cars responsibility to start, not the drivers.......or do you watch too much Flinstones
