* Average car speed: Most cars travel at 60-70 mph on highways. 215 mph is more than three times faster than that.

* Human running speed: The fastest humans can run about 28 mph. 215 mph is nearly eight times faster than the fastest human runner.

* Sound speed: The speed of sound is roughly 767 mph. 215 mph is about 28% the speed of sound.

To give you an idea:

* A car traveling at 215 mph would cover a mile in about 17 seconds.

* It would take less than 10 seconds for a car at 215 mph to reach the speed limit of 65 mph.

Think of it this way: 215 mph is a speed typically associated with high-performance race cars or aircraft. It's significantly faster than everyday speeds you encounter in your daily life.
