Location platform Here Technologies calculated how far one hour of driving can take drivers out of major American cities starting on Friday at 4, 7, and 10 pm.
The worst of the worst is Boston. Via WaPo:
In Boston, you can drive a full 20 miles farther if you leave at 10 p.m. than if you leave at rush hour. Twenty miles might not seem like much, but in tightly packed New England, it's the difference between being stuck in Massachusetts or escaping to neighboring Rhode Island or New Hampshire.
Compare that to Houston — a city with more than three times as many people as Boston — where you can travel almost 50 miles in one hour no matter what time you depart.
