If you're going to license it as a low-speed vehicle (limited to 25 mph federally by Federal Motor Vehicle Safety Standard No. 500), you will be barred from many surface streets with speed limits of greater than 30 mph, depending on state law.

In trying to map out whether I could get from my house to my local airport exclusively on roads with 30 mph or lower speed limits, I had a hard time proving it. All of the obvious routes that I actually use had at least one segment with a speed limit of 35 mph or higher, which is barred by my state law (Massachusetts).
