Three questions for our time

OK, so these probably just serve to confirm my decent into old fartery, but I have to ask: 1. What's the point of blueberries? They don't taste of anything except sugar and when baked turn into a purple stain; 2. Why do deodorants need a 'safety catch' all of a sudden? When was the last time you accidentally shot yourself in the armpit? 3. Why can't new cars have proper handbrakes? Flipping a little switch doesn't give the same sense of secufryt and driving away with the brake still ostensibly 'on' just feels weird.
