Not sure how old you are but I spent half my adult life dealing with a government regulated Taxi medallion system and the other half using Uber in multiple countries and I’d 100% take “post-VC” Uber over old taxis every single time.
FWIW they both still exist so you’re free to choose, which is the nice thing about competition.
Pre booked airport black car taxis have always been a niche within the wider system for a good reason. Uber’s fluid system is not perfect at every scenario.
