Actually this vehicle is for a competition and it won't be hitting the road much other than the few days in which the competition will take place.cpscdave said:Most newer cars already have seatbelt sensors built in. Could you hijack that signal??
My car even goes so far to have a weight sensor in the passenger seat to suppress the alarm when no one is sitting in it.
However from a safety standpoint a kill switch such of this might end up being more dangerous. What happens if the sensor fails when you're driving down the highway? Or if you've been out camping in the middle of nowhere and the sensor fails?
So you're saying you don't care if it's really dangerous during those few days?TheNerdyGuy said:Actually this vehicle is for a competition and it won't be hitting the road much other than the few days in which the competition will take place.
no, he is saying the solution doesn't need to work for 30000 hours before failure, just a few.phinds said:So you're saying you don't care if it's really dangerous during those few days?
Sure, and I agree it's almost sure to be safe but "almost sure" isn't all that great when your life could be on the line.donpacino said:no, he is saying the solution doesn't need to work for 30000 hours before failure, just a few.
Actually there is no threat to life,its an electric motor driven vehicle that would barely cross 25kmphphinds said:Sure, and I agree it's almost sure to be safe but "almost sure" isn't all that great when your life could be on the line.
That proposed modification could be contravening your contractual agreement with your insurers. You would be advised to ask them or you could find you were not covered, if you were to have an accident and the assessor were to poke around. In the case of this particular vehicle, I would think he may be very interested in any mods you had done.phinds said:Sure, and I agree it's almost sure to be safe but "almost sure" isn't all that great when your life could be on the line.
If I were going to use a parachute just once - tomorrow - I would want to be pretty sure it was going to work and the 30,000 hour figure would be the one to give an indication of risk. Just as with radio nucleides, even one with a half life of 1,000,000 years could go off now. With a potentially lethal thing like a competition car, I would have a similar attitude. For a radio set or a gas cooker, I might be a bit less fussy. But this is bordering on a duty of care issue (for other competitors) and, as such, should be treated with a fair level of seriousness. You may find something in the competition rules to tell you what's acceptable or not.donpacino said:there is a large difference between a design that will olny last a few days, and a design that is 'almost sure.'
If you were going to use a parachute 30,000 times that would be one thing, as you need to worry about the durability of the cloth, effects of repeated use on the lines. If you plan on using it once, and you KNOW it will work a few times, then that is fine and safe, because you don't need to worry about the cycling effect.sophiecentaur said:If I were going to use a parachute just once - tomorrow - I would want to be pretty sure it was going to work and the 30,000 hour figure would be the one to give an indication of risk.

I have a worry that this is outside the remit of PF.
Even worse than failing, what if the sensor works?cpscdave said:However from a safety standpoint a kill switch such of this might end up being more dangerous.

This is a massively bad idea. What made you think this idea would help you win the competition?TheNerdyGuy said:Actually this vehicle is for a competition and it won't be hitting the road much other than the few days in which the competition will take place.
A seat belt can act as a kill switch by interrupting the flow of electricity to the engine's ignition system. When the seat belt is not buckled, the kill switch is activated, preventing the car from starting.
It is not necessary, but it can be a useful safety feature. It can prevent someone from starting the car without buckling their seat belt, promoting safe driving habits.
Yes, a seat belt kill switch can be installed on any car with an electronic ignition system. However, it is recommended to consult a professional mechanic for installation to ensure proper functioning.
One potential risk is that the car may not start if the seat belt is malfunctioning or not properly buckled. This could be a major inconvenience in emergency situations. Additionally, it may not be effective in preventing accidents caused by distracted driving.
Yes, the seat belt kill switch can be overridden by bypassing the system or using a fake buckle. However, this defeats the purpose of having a kill switch and can be dangerous if the driver is not wearing a seat belt.
