>However, steering and brakes are mechanical systems in Hastings' 2013 Mercedes C250 (like almost every other car), and cannot be electronically overridden. about ABS brakes (and thus absence of direct mechanical control by the driver) other people have already explained. The speed is controlled by electronic throttle control. Mercedes was among the first and brought drive-by-wire decade ago. >The steering wheel is connected directly to the wheels, and can't be controlled by the electronics. ever heard about electric assist steering? Mercedes does have it on the C250. And btw, the modern cars don't explode. Poor Mercedes when guys like this will come into play http://www.usautoinjurylaw.com/types-of-accidents/explosions-and-fires/ http://www.usautoinjurylaw.com/types-of-accidents/explosions... The reputation and perception is half the price of a Mercedes and this accident makes a dent in it (on the related topic - how much Toyota suffered for a runaway acceleration).

> ABS brakes Correct me if I'm wrong: ABS doesn't cut off pressure to the brakes but instead relieves extra pressure. At no point can the ABS module ever fully cut off brake pressure that's being hydraulically applied by the driver. Incorrect? > electronic throttle control Yes, but my point was that regardless of what the throttle was doing, brakes can counter. If he was alert, he should have had reasonable time to start braking as the throttle opened up. > ever heard about electric assist steering? Mercedes does have it on the C250. Thanks -- this is a good catch. > And btw, the modern cars don't explode Agreed.

At no point can the ABS module ever fully cut off brake pressure that's being hydraulically applied by the driver. Incorrect? if relief valves are kept open (instead of open/close/open/close/... like during normal ABS operation) i don't think there will be any effective braking force.
