A Riddle

Ever hear of the riddle about a farmer that had to cross a body of water with a chicken, fox and a bag of feed. And he can only take one at a time across. Well, just the other day I came across a similar experience:

A lone driver has to get two cars from apartment #1 over to apartment #2 which is located 3 miles away. It's 95 degrees out and there is only one driver to do this. How do you do it?

Well all I could come up with was the only driver gets into car #1 and drives it a block, parks and walks back to car#2 where she then drives it two blocks, parks and walks back to car#1. Leapfrogging the two cars every block or so, the lone driver finally arrives at Apartment#2.

So what do you think?

Thankfully, the driver had a sister and brother-in-law come to the rescue where they drove one car and she drove the other so technically the driver never had to prove whether this was the right answer to the riddle.
