Uber CEO balks after a reporter tells him the cost of his 2.9-mile Uber ride: 'Oh my God. Wow.'

I mean, it's an hour's walk for the average person.

And that's assuming safe neighborhoods, actual sidewalks, good street lighting (if at night), pleasant weather etc.

Not to mention shoes that are actually comfortable for long walks. You'd be surprised how many people don't have that kind of shoes, and an hour's walk in their regular shoes would give them blisters.
