How was your experience?
I'll first go over driving the car and then the experience of the tour. The car rides like a moped, but with two wheels in front like a car. And so while it was bumpy, you learn quickly that the ride can be smoothed out by adjusting your direction so that the front two wheels go around any small bumps or dips in the road. The GPS-guided (audio) tour works very well and gives more than just directions since you also get a sense of humor, a little history, and many cool stops pointed out along the way. The car takes gas, but batteries power the audio tour and are used for starting, turn signals, horn, etc. If you lose power there is an auxiliary battery in the trunk, and if that loses power there is even a hand crank to start the engine just in case. Many pedestrians along the way took pictures, wanted to stop the car for a joy ride, and even signaled for hitchhiking (despite there being two of us in the two-person car!) But you should not stop in any one given place for too long since the two hour tour takes the full two hours. If you want to stop longer at the happening sites you can always retrace your steps in your own vehicle afterward, which is what we did. So while we had both been to nearly all the sights in the San Diego main downtown/Balboa Park, Presidio, etc. areas, this tour took us through many of the less traveled places in definitely a less conventional way. Highly recommended for visitors and long-time San Diegans alike!
