i a bad had experience to(トンスンドン)の鍵my car key in the car in kutna hora、czeck、where is 100 km away from the car rental office、I have to take train and bus back to the office to take spare key, it wasted my 7hrs journey, so be careful with your key when you take something in the car! it is a really good experience to drive car at nearly all empty towns without red light and passengers, my whole journey fuel consumption performance is fantastic because of this,which is only at 6.1L/100km. this result gains even including on the non−speed limitation highway in Austria where I drove in 140−160km/hr,this speed is not economic for fuel consumption. I really like the road across with round plate in stead of red light,you don't loss too much speed when you pass through them. touring with car made my travel in a very high efficiency comparing with public transport,that is why I am able to go almost everywhere in two countries within 15 days. the many beautiful lakes in Austria, Alps Mountain, forest,and the wave landscape and curved road give me very deep unforgettable memory。
