If I had a dollar for every person I see driving around in thick rain, or in full darkness with their lights off, I could probably buy a nice new macbook air.
It's truly shocking how many people are far from alert and observant while driving. Either because they really don't care, or they've been conditioned to take driving very casually.
I use the number of cars I see driving with their lights off as sort of a gauge of how many 'bad' drivers might be on the road, in a 4-5km radius, at any given time... And it's a percentage that is too damn high. My working theory being that if people are putting a car into gear and getting into traffic without checking that their lights are on first, they're probably far from alert and ready in all other driving scenarios as well.
