A helmet is a safety precaution, and you're an asxhole for making fun of anyone for wearing one anytime, if the guy wants to wear one to drive to work, or to the grocery store - more power to him, you've obviously never been involved in a high speed accident (maybe you can't go 'high speed'), I've been involved in 2, neither were my fault - once at about 86mph on the interstate, dude changed lanes into my left rear quarter panel, car turned left, directly into the cement barricade that keeps you from crossing into oncoming traffic, turned onto the passenger side, and slide roof-against-barrier for about 250-300 feet - I don't know about you, but, I go faster than 85 at the track, and that was one of the scariest things that has ever happened to me, I had on no helmet, and the impact from the airbag was enough to make me wish I did, it hurts, not as bad as your skull bouncing against the B pillar, but, it still hurts.
I also managed to be acting like a moron one night on my bike, it was very late and I had assumed no one else was out, apparently a 16 year old girl had assumed the same thing, she rolled through a stop sign and pulled onto the main road directly in front of me while I was doing 90, I panic'd, locked up the brakes, she did too, I managed to miss her car but, lost it - and had a nice encounter with the pavement, the only place on me that wasn't protected by gear, were my legs (stupidity on my part, it was hot, I chose against it), and they got fxcked up. My head, didn't even hurt, even though my helmet was cracked in 2 places from the pavement.
Helmets save lives, plain and simple, whether it's on a motorcycle, on a NASCAR track at 200mph, or some kids 15+ second car at the track, and I return to my previous statement, if you make fun of someone for wearing safety equipment, you're an asxhole.
And for the record, kiddo - it's pretty dumb to show your asx by making fun of someone for wearing a helmet, and then expect no one else to respond to it, simply beacuse you're "done bxtching", you're going to get heat for stupid comments, so expect it. Your first response, from YZBot was dead on, and you're going to run into a lot more of them if you insist on being immature.
EDIT: Also, what's this doing in tech? Obviously your helmet concepts aren't the only time intelligent thoughts escaped your grasp.
