I agree that data collection is a good security measure in this case. But privacy friendly does not necessarily mean there is no data collected.
Important is that nothing is shared with 3rd parties and all data is well protected.
Safety features nessaseraly demand open and auditable by third parties.
We need to be able to ensure that abusers aren't hopping around companies abusing passengers or drivers, for example. It's hard to do that with complete privacy.
It's one of the cases where strong regulations so third parties can't do things with your data is important, but also sharing that data to protect yourself and others more vulnerable than you is important.
What's wrong with taxi services?
From a client perspective Uber and Lyft don't solve any issue that taxi services don't. They may be more convenient/accessible by providing an app, but that's not an unsolvable issue.
But from a privacy perspective taxis clearly have a leg up since you're an anonymous customer.
Convenient hailing. A phone call works okay if you're home, where there isn't much noise and you speak the local language, but a web form is often much easier and less error-prone in other situations.
Efficient coverage. Many areas either have sparse taxi coverage, or multiple taxi companies competing in an area, and if the one you call doesn't have enough drivers available and nearby, you're stuck waiting unreasonably long even if there are other ride options with better availability.
Up-front journey-specific prices. We now have the technology to see what the total cost will be before we commit to a ride. We should be using it.
A single point of hailing, where I can submit my location and destination, and be presented with my ride options from all the available providers.
Accurate pick-up and drop-off time estimates. Even better with real-time taxi location.
Quick arrival.
Automated ride-sharing coordination among strangers.
Fuel efficiency incentives. Most taxis I've taken have been heavy vehicles that guzzle petrol, passing the expense on to the environment and the customer.
I think most (maybe all) of this could be solved by something like a clearinghouse for taxi rides, effectively federating the various taxi services in an area, with a web app available for hailing.
So true! In Germany we have Blablacar and Flixbus / Flixtrain, which have soo much better services to travel cheaply. But its proprietary "install our app" garbage
