Im no aerodynamics expert so humour me, lol...

Just wondering (as been out messing with fitting new mirrors, spoiler, etc) why mirrors on cars etc dont fold themselfs back at high speed, ie the wind pushes them back.

I mean, its not hard to do it with bare hands, idve thought the wind would do it just as much, but it dont.

Same as front bumpers, on 3dr's, R32s, etc, the bumpers are pretty flexible, can bend the lower centre section with ease with bare hands, why dont the wind do the same or more when at BIG speeds?

At first i had visions of my fancy mirrors n spoiler getting torn off the car at 180+mph, lol, but if it cant fold back foldable mirrors then it sure wont do that...

But why? Put you hand out the window at big speed n it nearly takes ya fookin arm off!

 

thats why they are designed to be aerodynamic!!!

the whole car is designed to flow air where the designer wants it to go.

 

just use some 6ft long screws on the spolier steve and your be ok

If it does come off tho, make sure im not behind you as it will do some serious damage

 

thats what i thought BUT how come the windscreen wiper starts moving to the middle of the screen when going over 130mph in my old pug? Surely that doesn't have more drag than a wing mirror

 

Most mirrors arnt really aerodynamic tho (Tho my new ones are)

Same as 3dr bumpers, slab front and quite flexible, yes the air goes thru the holes and around it, but its soft enough idve thought itd get pushed in, same with mirrors, which are often jus slabs n only held in place by spring loaded clips.

Obv they do stay in place, but i jus wana understand why (in a semi-technical way), lol
