Yeah, they should have lights, but drivers have no right to dictate people's clothes while people are still driving around in black cars, especially when some of those have the wrong number of lights or sometimes don't put the lights on at all.

As for responsibility, let's be proportionate. A rubbish cyclist might kill themselves, but rubbish drivers can kill everyone and probably damage buildings and other infrastructure too, so it's probably justified if drivers have to pass stricter tests.
