It seems like so many of the apps that come to dominate just make up for shortcomings unique to the US that then, with money, take over the rest of the west for no good reason other than scale to get 25 people at the top of those companies rich.
I’ve never seen the need for Uber. Taxis have never been an issue in the UK and the most successful firms in the city I lived when Uber was starting out already had apps. Literally the only thing Uber had going for it was masses of money to undercut the market and advertise to younger millennials - basically their excess money allowed them to get better distribution and cheat the market.
I’ve used Uber three or four times in my life and each time was a worse experience than a taxi.
