Look out for Czech drivers, who were recently, unofficially voted the third worst in Europe. They don't stop at zebra crossings and are quite happy to run you over at earliest opportunity. Pollution in Prague is average with quite dense traffic during the week. Rush hours are between 2 and 5pm. If you are looking to buy a car in Prague, it may be a good idea and a bad idea, depending on where you are from. If you are from somewhere where cars are cheap, then maybe it's not such a good idea, but there is a good range of cars in Prague; cars from all over the world. Becareful when hiring a car. Make sure it is the car, not you, that is insured. Sometimes, if you wreck the car, you will have to pay for the repair; so shop around.
