So on my next trip home I will have cause to use a car service several times. Going to be mainly in the Sheffield area. It has been suggested that the Uber Exec service is quite good. So I went to download the app and sign up. Having never used them before getting a first page request for my credit card, made me pause. A quick search online bought up the usual suspects of "the end is nigh"

So My questions

Are there any tricks to using Uber for a newbie?

Millions I presume do enter their credit card details before using , should I jump out the window as well?

Has anyone used the exec side in the UK at all?
