What kind of transport will be the best for sightseeing?

Sightseeing is one of my favourites activity. Mostly I just go for a walk and watching but if I would like to sightsee during my vacation, I must think about different means of transport. I must feel comfortable and see as much as possible. And, of course, get the ESTA, if I want to visit United States. Learn more here:

Electric scooters – new method to drive through the city
