Driverless cars were the future but now the truth is out: they’re on the road to nowhere
(www.theguardian.com)
This is a most excellent place for technology news and articles.
That's easy:
You don't have a good self-driving car (yet).
Your comparison is: either being on public transport or on a level2/3 autonomous car, where you still need to watch traffic at all times and be ready to take over the steering anytime on very short notice. That is proven to be even more stressful than driving a normal car.
And that's going to be your choice for these next 100 years or so.
