We had rented a car from San Francisco to San Diego. My wife was going to drop off the car at the airport. We asked at the hotel (by the harbor near Little Italy) how to get back. 'Uber'. We then looked at the map and realized it was about 0.5 miles away, with sidewalks the whole way. She walked. My Houston experience was when I wanted to go to a nearby salsa place. It was about 3 blocks away from the motel, as the crow flies, but the other side of the interstate. It required a car to get there.
