Generally not really a safe practice, especially where traffic is going fast. The speed differential between bikes and cars makes it very difficult for both driver and cyclist to react. E.g., car moves at 60 kph and cyclist moves the same direction at 25 kph. Relative speed is 35 kph. A good chance cyclist would survive that crash. Car at 60 kph and bike moves at 25 in opposite direction gives a relative speed of 85 kph. Cyclist will not survive a crash at that speed.

As for motivation, I don't know. Could be ignorance. Could be convenience.

Runners run this way on some roads. But the speed differential isn't quite as severe, and runners ca react much more quickly on foot to dodge out of the way, and also less chance of them losing control/balance on foot.
