If there's such a problem with speeding nowadays, why don't they build cars that can't exceed the speed limit?

Answer 1

Think about it - the problem is not excessive speed overall, but inappropriate speed. If you limited cars to 70mph because that's the motorway speed limit, they would still be able to go 70 in a residential area where the limit is really 30 - obviously still dangerous. I would imagine more people are killed in 30mph zones than on motorways.

Answer 2

Cars are so much safer now, I think the speed limit on the outer two lanes of a motorway should be 80MPH, vehicles can be fitted with after market speed limiters, (for example company car fleet owners could ask for these to be fitted to their cars).
Next year, a new law comes into force which will see speed limiters fitted to all vehicles over 7.5 tonnes, this may include some Mercedes Sprinter or Iveco or similar vans which can easily do 90MPH right now. Sprinters are very quick vans.

Sometimes 80MPH is good, to get you away from a bunch of vehicles travelling close together on a motorway, etc.

But restricting a vehicle to 80 or 70 just to reduce accidents is fairly useless, if the driver is on drugs, or driving past a school at 50MPH, or drunk or un-insured or has bald tyres or bad brakes, what use is a limiter then?.

Restricting all vehicles is not the answer, educating these sort of drivers and installing an amount of responsibilty and discipline in their minds might help more! It would be better and more successful than installing 100 million speed limiters. Education would reduce road deaths.

Answer 3

How do you think one would go about building a car which didn't exceed the speed limit considering the different speed limits we have and the different places we have them.

You could be travelling down a piece of road and the speed limit could change multiple times. How is the car going to detect this and adjust the speed accordingly? The car doesn't have eyes to see the speed limit signs on the side of the road!

It's the driver which needs to use their brain and drive at the posted speed limit.

There is too much emphasis these days on having the car control the driver and not the other way around.

Answer 4

The problem isn't with speeding, it's with getting caught! Seriously, if people would pay attention to driving instead of chatting, eating, watching the scenery, re-programming their sat-navs, making & receiving phone calls etc. we could all safely drive at any speed because we can actually train ourselves to process critical information very quickly. I hate to heap praise on the feds but Police Class1 drivers spend years getting to such levels and only occasionally foul up, albeit that it's usually big-time and gets all over the press.
Trouble is, people's self belief usually outweighs their ability - just look at tailgating if you need proof. At best, people think the bloke in front won't stop suddenly, at worst, they think they're smart enough to out-brake him.

So, we're all stuck at 30/50/70 or the speed of the middle lane hog, simply because the honourable Joe (or Jane) Public thinks driving is what you do when there's not someting else to pass the time on a motorway, rather than a skill to be learned, polished and perfected every time you get behind the wheel. It's just an extension of the old thing about getting the society you deserve - if we tolerate mobile phones in cars, we have to pay by being made to drive so slowly that we can take down messages and send texts at the same time. "Speed don't kill. Bad driving kills"

Answer 5

They do, stupid little powered rickshaws Sinclair C5s etc, but nobody buys them, really there is no problem with speeding, the chances of an accident are millions to one the only real problem is police taking everything so seriously and closing the roads when someone is killed, why bother they are dead, closing the road wont bring them back will it.
Trouble is with todays increasingly heavy but streamlined car enough power to climb motorway gradients at 70 in top gear comfortably gives a top speed of about 130mph, 30 years ago it would get about 84 mph .
But really the accident rate is so low we should be raising speed limits to give us all more time to do things other than sit on motorways.

Answer 6

Unless it is law, then no-one would buy them, so the car manufacturers will not build them. If there was a way of limiting cars speed to each speed limit that the car was in, then the government would not receive any money for speeding fines, and that would be totally unacceptable!

Answer 7

One simple reason. Growth and development is painful. If we never had the need to stop cars from high speeds we would never have developed Ceramic disc brakes, ABS, Traction control, ECT DSTC etc. And I suspect the lack of these systems would result in far more deaths than result from speeding. If we never have a need to improve what we have we won't, so unless you never want to see the wonders the future may bring us then I suggest you stop asking such stupid questions.

Answer 8

there is continuously a demonstration! % decrease indications are revealed the position the speed decrease transformations - there are not the different % decrease indications until eventually the decrease transformations back (except for from time to time you get the small repeater indications). So there is continuously a demonstration - that is the most suitable one you exceeded, and that % decrease continues to be in pressure until eventually you bypass yet another one - inspite of the fashion of highway you're on, or the fashion of junctions you negotiate. The nationwide % decrease in straight forward words applies once you bypass a nationwide % decrease signal - no longer purely once you bypass onto a diverse style of highway. So, to reiterate - there are in straight forward words % decrease indications the position the decrease transformations (except for repeaters) - so that you recognize what the speed decrease is through remembering the most suitable signal you exceeded.

Answer 9

can you imagine how slowly things would move if we could only go the speed limit? We'd have little slow polks it would take 3 hours to go what normally takes 2 1/2. What a hassle that would be in our busy lives. However it might save a few.

Answer 10

b/c most of our cars are made from the ideas from other countries. plus it is common sense to do that and most people that build cars dnt have common sense
