We put up with a lot of previous things that time has proven unsafe, like brakes, no safety belts, good lights, etc.. But there are many things we can do to mitigate some of the most obvious and dangerous. Safety glass is one of them. A stone tossed up from the road or falling off a vehicle coming from the opposite direction, or even a bird can crash through that plate glass and the blood squirting out of your juggler is going to ruin your upholstery. Oh well, like they say. Ignorance is curable, but stupidity is terminal! My condolences to all those out there that are not still in one piece.
