When I lived in Cali, a couple of Canadian friends had a theory about why DRLs will never become law. It's an easy way for the CHP to pick up drunk drivers - invariably they forget to turn their lights on. And the more I watched drivers, the more I believed it to be true...
Here in Sydney, you drive with your lights on and people think you're an idiot, or a
pr*** in a Porsche...
