one day i started to back out of a spot (in my old car a few years ago) and some dude was doing like 50-60mph in the parking lot at work, no way i could have seen him coming when i started. luckily my peripheral vision saw something, and i hit the brakes to have a second look.
he went skidding by before i could even focus...
last weekend i caught some lady doing around 60mph in the residential section a couple blocks from my parents' place while visiting. i started to go through the 4-way stop signs when i smashed the brakes because it occurred to me her boat would probably not stop in time (and would hit my Fit's driver side). yup, she skidded all the way through the intersection... she gave up trying to stop on the other side and kept going.
i count my lucky stars!
