Personally to prevent speeders..........
Speed, in and of itself, is not dangerous, although it does usually increase the extent of damage in a collision or crash (can't deny E=mv^2) Speeding needs to be taken in context of driving conditions, traffic flow and volume, and reason. 5 mph, or even 10 mph, over a posted limit, when weather is good and there is little traffic, is entirely safe, with a trained driver
Automatic transmissions scare the sh*t out me, especially in parking lots frequented by the very elderly who sometimes press on the wrong pedal intending to brake.
So, are you saying to give the old folks a stick and another pedal to make things easier for them? If they can't handle an automatic, then a manual surely isn't the answer. If it were possible, put more distance between the brake and gas pedals, then MAYBE they'd hit the right one.
Edit: there are new systems that automatically apply the brakes if a crash is imminent. I saw a review on "5th gear" (all european models) and those systems seem to work well for the most part. At least they could help with reducing injury and death. They're definitely not a solution to anything.
I certainly don't want MY car to start thinking for me. Training and vigilance when you're the driver is the better way, unless you eliminate the driver altogether, and then, I'm taking the train. When cars have so many built-in "safety features", people inherently begin to depend on them without consideration of their surroundings or the complete picture. In other words, we get lazy.
I think there are entirely too many distractions today for drivers. Multitasking is a phantom and a lie; the human brain can focus on only ONE task at a time. What we call "multitasking" is actually a shift in focus from one thing to another over very short periods of time, and minimizing how many of these shifts occur dictates how much we can pay attention to the others.
I'm not only a staunch proponent of "NO texting while driving", but also "NO cellphoning while driving" There is nothing so important you can't let it go to voicemail until your next stop; if you are expecting something Earth-shattering to come in, stop the car first and then answer the phone. I've followed people for 15-20 miles and the've had the phone to their ear the whole time. tell me they're paying full attention to their driving.
Enforce minimum speeds. People that go under the speed limit only endanger themselves and others.
I'll buy that one, but sometimes driving the posted speed can be too slow, given some circumstances where traffic is flowing substantially above the posted limits.
I feel more dire consequences should be written into some traffic laws. Such as:
Immediate and permanent seizure of your car for DWI, in addition to even lower blood-alcohol limits, and NO second offense arguments. If you've had one DWI, the second one should have mandatory jail time, no plea bargain, no appeal. Heck, I'd be in favor of that for a 1st offense.
Loss of license for 1st texting-while-driving. Minimum of one year suspension, 90 day impoundment of vehicle.
Aggressive driving, impoundment of car for 90 days, $500 fine, and car not returned until payment of fine.
See where I'm going with this? Take people's cars when they prove they can't stay within the law.
Now, go to "the other side". Better training and more specific parameters for law enforcement personnel. Take most of the individual judgment out of the equation. I've talked to several HP in my state; they will not say how much leeway they personally give on speeding, but they do say, to a man, that it is their individual judgment on what constitutes a violation of a particular traffic law, even if there are specific criteria written in the vehicle code. In other words, one LEO might allow less leeway than the stated provisions of a law than what the specified provisions are. Then it's up to YOU to defend yourself in court, which ain't free, whether you beat it or not.
US drivers have it easy. License is cheap, enforcement is uneven. We should take the European model, more specifically, the German one. License is more expensive, driver education more strenuous, enforcement more equitable.
