I've actually driven a snow mobile and it's great fun. The snowmobiles are a hobby wich many Icelanders have.
Those jeeps can reach about 1000 hp. when the nitro in them is in a full boost.
If you're going to try to use one of these on the thames you'll have to have a good starting point because they don't flote and if you loose your speed down you will just go down with the car.
