It worked great! Healed in 6 weeks what nature on its own hadn't done in 4 months. The $4k I have no problem with either. Testing and validating good science costs money and avoiding surgery is a good investment. The only thing that bothered me was throwing away something that I knew was still perfectly capable of healing a person. .
The only thing I've got a problem with is that a lot of that money goes toward liability and future (and present) litigation. It's a capitalist economy, and I'm a big fan of people inventing things that work and making a lot of money off them because they hold the patents. I'm less enthusiastic about lawyers who file suit when a bone wouldn't have healed anyway, and make a lot of money off the situation.
I think this is a valuable safety device and probably shouldn't be dismissed as gizmo junk. Todays cars are capable of much more rapid stops than people will push them to. Some accidents will be avoided altogether with this tech and others reduced in severity. When the biggest downside is a good seatbelt check for the rest of the family as a result of a twitchy drivers foot I have no problem with it.
Am I really the only one who doesn't like this thing? I'll concede the point, that it may help a majority of drivers. I just wish I could turn it off. And besides, and back to the original point of the thread, it's just another shoddily manufactured, proprietary electronic thing that's going to break at some point, and cost hundreds of dollars to fix.
Anyway, if you wanted to make the roads safer, you could do it in 2 easy steps:
1. Intensive driver education. 40 hours in the classroom, 40 hours on the road, including a skidpad.
2. Make cell phone use illegal while driving, with or without a hands-free device (which doesn't improve safety). Cell phones increase the accident rate by 400%, the same as driving drunk, so why do we have MADD and not MACP?
