Most cars will stop almost immediately without coolant.
You can drive quite long without coolant, I rode 30kms without coolant, because my radiator hose burst and the thermometer wasnt working, then suddenly it was redling, drove to a nearby gas station, filled it with water and all worked fine. Plus you'd have to be infront of the car not beside it to hit the radiator in the first place.
So what does attempted murder bring over on that side of the atlantic? With a previous criminal past?
And I hate it how ADHD, ADD, Bi-polar is used to justify criminal behavior. I was diagnosed with bi-polar by some psychologist, hasnt really affected me much, sometimes I get creative, sometimes I feel down. Its not like I'm out there trying to kill people, just beacuse I had a bad day... jeez.
