I think our English divers/drivers will see the problem with this air powered Reliant and it isn’t air fills! Cars/trikes with one front have a bad habit of rolling over on sharp turns. There is even a Reliant racing series that’s more like a demolition derby and fun to watch as the cars roll off the corners :)
Now an air powered boat with a long hose would be good for us as long as the J-valve leaves enough air to get home :)
