[quote]I’m sure most cars that are DBW don’t have throttle cutoff when brakes are applied including domestics (yet). Things are about to change.[/quote]
All German cars have it, and they had it at least since 2000. Newest Toyotas and Lexuses have it (unfortunately, neither the Lexus that crashed in Santee last year, nor the Prius that made headline news this week, were new enough). I’m not sure about domestics and other Japanese brands.
The puzzling question is why it’s not a universal feature. All modern cars already have brake sensors that report to the ECU (that’s how the ECU knows to cancel cruise control when you step on the brake). It’s only a matter of programming.
