“Kind of scary to end up in the hospital backing out of your driveway.”
Guess it depends on how much enthusiasm you’re backing up with ;-).
The reverse gear has a high ratio, that means that the reverse speed is limited to something around 10 mph even if you redline the engine. Regardless of the enthusiasm, it's impossible to go faster than the car allows. Perhaps someone who owns an Escalade will tell how fast it can go in reverse. This car's safety is rated five stars out of five (driver front.)
