(this is a rewritten version of the original one)
I was recently thinking of a way to stop car accidents. So I started googling around looking up information and found that theres just the basic airbags and seat belts that are the main things saving us from dying in the accident. They are making cars
so they crunch more safely but your car is still getting wrecked isn't it?
You get into your vehicle in the morning to get to work. When you sit down a voice informs you to remember your seat belt and slip on your VSD. A VSD would resemble a heart monitor detector, the ones that slip on your finger and detect your pulse and what not.
Your driving down the road and you notice the light at the intersection up ahead is turning from green to yellow. You speed up to make the light and in the middle of the intersection your pulse increases a little bit but not enough to matter. When you glance to your right you see a car traveling around 50 - 60 mph straight towards you. Your Adrenaline starts pumping and your pulse sky rockets. The VSD detects the sudden change and drains the battery creating a 5 - 10 second magnet push around your car. The push stops the car from crashing into you at high speeds.
A back up battery that is maybe a fourth the size of the original one is saved for airbags incase you swerve into a tree or something else that is nonmetal.
This would mean that car companies would have to install all the essential metals somewhere in the car and the necessities of a magnetic field.
This idea is completely plausible considering magnetic shields have been used. I haven't found anywhere that it is used like this so the idea is original, atleast i think anyways.
*thanks to [pooduck] for the extra battery idea*

[7th], Welcome to the Bakery and all that. You have achieved some good input previously but could you please revisit this one and make some sense?

Can I ask how the airbags would activate if the battery was drained of all power? |
|
| |
A well-turned set of rollerblades and the right clothes in sight and I would drain my battery repeatedly on many calm and uncomplicated drives about town. |

OK, where do we start?
(1) Using the driver's physiological
responses as a crash warning is flawed.
You need at least a couple of heartbeats
to detect an elevated pulse rate; blood
pressure does not rise instantaneously;
and elevated adrenalin levels would be
hard to monitor (you going to ask the
driver to insert a needle?) and would be
wayyyy slow. By the time you detect
these physiological changes, the
accident has already
happened.
(2) The car that
does the most damage is often the one
you didn't see.
(3)I am pretty
sure that your 'magnetic shield' is bunk.
If you can repel a non-magnetized lump
of metal at all in this way, I'll guarantee
it'll take more oomph than you can
provide.
(4) Any force you
apply is going to act equally on you and
the oncoming vehicle. Do you really
fancy having your car pushed backward
into a pedestrian by the truck that
happens to be passing, just because
you were startled by something else at
the time?
(5) Your magical
magnetic shield is going to repel any
nearby steel object. So, in your
moment of panic, you will send all
nearby vehicles swerving away from
you, and catapault nearby wheelchairs
and zimmer-frames into the
distance.
(6) Depending on
how your magical shield works, you
may also expect to be sued by anyone
nearby who's carrying a laptop. And by
anyone who happened to have keys in
their pocket at the time.
(7) I
have more. Ask. |

for example:
(8) if you are
driving over anything large and metallic
(tram lines, buried pipework....) you can
expect to become airborne immediately
after the collision, and
then land on whatever hit
you. |

haha ok I guess this idea is bunk, thanks for the brutally honest truth though. |
|
| |
It's a rough design but it could be improved somehow. |
|
| |
GPS feeds computer surrounding car's location (while broadcasting its own) & speed & activates brakes to prevent accidents? |

"Hey man, watch what my car does when I down this can of Jolt cola..." |

What parts are you going to remove in order to add these huge magnets into the car? If you have a magnet that big, how does it keep from attracting the backside of the other magnets around you? Magnets are di-polar. |
|
| |
Cars are heavy enough as it is, and ironically getting heavier because of more severe protection requirements coming down the pipeline. |

//haha ok I guess this idea is bunk,

I respect. I suspect I would not take it
so well :-) |
