If I start "driving" away from earth at 100 mph and never speed up, won't I eventually get as far away as the rocket and therefore escape?

Yes. What is different, and what was not made clear perhaps, is that escape velocity is the velocity required at the start of movement for un-powered flight, as for example if you were to throw a stone. If you have enough fuel, then you can escape as slowly as you like. When I walk upstairs I am escaping the earths gravity a tiny bit, but I can't go on for long.
