In a parking lot, this is more than enough time to jump the curb and plow through the window of a store, but on the highway, it just isn't going to happen for so long as to cause the car to do anything more serious than run into the next car in the line. We are hearing stories of people that stand on the brake pedal with both feet and can't get the car to stop. We have not explored the interaction of traction control and antilock brakes preventing the brakes from stopping a car with a throttle intent on being set to the maximum setting. We also have not looked at the issue of brake fade that comes from the brakes getting hot. If the brakes locked the front tires, the ABS would sense this and unlock them. The driver might keep his foot planted firmly on the brake pedal which has sunk to the floor, but the car still would not stop. The brakes get hot and fade badly, and the car wouldn't even slow down. I'm not saying this happened, I'm saying it's a variable that could lead to holding the brake pedal down and still running off the embankment at 100mph, or whatever. > Just as the brake interlock to prevent shifting into gear helps.

I drove cars for 30 years before I had one with a brake pedal interlock. Your elderly customer also drove for a very long time with cars that had no brake interlock, and he wasn't aware that his new car had one. My guess is that he wasn't aware that any car had one ... There is no inherent accident waiting to happen without the brake interlock. Brake interlocks were put in to prevent children from moving the car from P and allowing it to roll down the driveway, they were not put in to keep the driver from being an idiot.

Toyota's electric steering does not use an electric motor to drive a hydraulic pump. There are makes that use such a system, but Toyota isn't among them, and certainly the Corolla does not use that system, which is the model that is having steering problems.
