My gf and I live 15-20 minutes from central London by scooter, or 45-60 minutes by public transport. We'd take an Uber home from a restaurant in preference to public transport almost every time if it's on the same side of the city to our home.

Given that a meal for two will typically be in the £80 to £200 range for us, the Uber itself is not an enormous sum.

Together we earn over six figures GBP. It may be an earnings level thing too.
