A few years ago, while driving the rarely used rural back roads of western Ireland, surrounded by hedgerows that made it impossible to see another vehicle roaring down a crossroad, I wondered what was the probability of having an accident if I just drove through and would I improve my chances by driving faster?
Cars A and B are 20 ft. long and 7 ft. wide.
Car A travels at 30 MPH and one passes through the intersection each hour.
The road is 10 feet wide. The potential impact area should be assumed to be as wide as the road.
If car B attempts to drive through the intersection at 30 MPH, what is the probability of an accident? Is the probability higher or lower if car B travels faster?
