Many thanks for this detailed reply, this is the answer is was waiting for. Compared the costs of driving for uber here and hungary, well, i have to say, that all the costs are the same kind, but not the same amount. We don't have to pay high insurance fees like here, even if it's a must have to drive for uber. We have to provide a professional driving licence like a taxi driver and the cars must have MOT every year.
Followed up your deatiled answer, i think i will do something else, instead of uber here.
