I was a little worried after reading some of the 1 star reviews because a technical issue would ruin this, but it looks like that is the extreme minority. We were given the instructions by video and helmets then on our way within 30 mins of walking in the door. We went out first so a couple who were behind us followed when we decided to intentionally detour, so it may be worth having a quick convo with any other people who are there before you set off. The GPS is easy to use (all automatic) and to be honest you wonāt want to go off the obstructed path. We stopped off at a viewing spot for the bridge but didnāt do the full tour (3hrs?), the half tour is more than enough really. Get used to people taking photos of you at traffic lights, especially at the famous Lombard Street section. Theyāre really easy to drive, if you want to stop for a coffee or anything then itās straight forward, but as you are paying for your time I would use these to see the sights rather than as genuine transport.
Loads of fun and we got some great photos. Definitely the highlight of our few days in the city. An easy way to get to the Golden Gate Bridge, have a quick walk round and get that experience in as well.
