Imagine your riding home from work, all entirely normal, on a straight and flat road. A car attempts to overtake you, but when you're level with his rear wheel, another car appears coming the other way. The road narrows a bit so the overtaking car squeezes you towards the kerb, rather than backing out of the manoevre and tryign again when it's clear. There's quite a bit of grit next to the kerb, including some larger chippings, one of which you ride over. Said chipping 'pings' out from under your front tyre just as the overtaking car is backing off and you're level with his front pasenger side window. Next thing you hear is a load bang as the cars pasenger window no longer exists and the car is now going backwards like it's just developed air brakes…..
What would you do next?
