There's already 20 million supported cars on the road, that number is increasing year over year, and the derivative of that number is increasing year over year. Why would we worry about this?
1. Older cars have a lockout on steering after 10 seconds baked into the EPS firmware.
2. While newer cars don't have this lockout, adaptive cruise control (ACC) is only on high trims. Therefore low trims lack radar and (possibly) continuous duty brake controllers.
It should be better in a year or two when ACC is standard on Ford. ACC is standard on Toyota, Honda, Hyundai, Stellantis, and Subaru, hence that's where the effort goes.
And people say comma is confusing.
