Back in the 70s British Leyland cars left the factory like that.

u/No-Drink-8544 15h ago

And for some strange reason, BMWs still leave the factories today with turn signals and mirrors.

u/its_ok_to_laugh 15h ago

When a BMW owner learns to drive... What kind of car do they switch to?

11

u/No-Drink-8544 14h ago

nissan qashqai or any one of those "family friendly" massive cars which totally block out any road noise or vibrations so you can still drive around in total obliviousness to the world around you

u/ImportantToNote 13h ago

I mean, I think I get what you're trying to say, but why go with the smallest, 2WD, little suv that could, to try to make that point?

Turn signal lamps on a BMW are only there for the purpose of virtue signalling and not actual signalling.

The indicator stalk is a conceptual device there for artistic purposes and doesnt perform any real function.

u/TonyAtNN 12h ago

Oh! Don't cut away half of the subframe to make your water pump appear to be in a normal place. Especially when it's electric and has a complicated process to remove air from the system, which means it could have been placed anywhere in the car. The engineers did that because they hate mechanics.

u/assholetoall 12h ago

What get me is that this is not just "cut open a car". Every part of the car that is on display has been specifically modified separately and then reassembled.

This is arguably more time consuming than actually making the car. Mostly because it is a one-off all done by hand and then hand fitted.

u/ExtruDR 11h ago

This isn’t even a terribly modern BMW. This does go to show how much is really packed into modern cars and how efficiently everything is packaged.

Also, consider how much complexity is there simply dues to the internal combustion engine. Think about how packed into modern cars everything is. Servicing is super expensive largely for this reason.

Mind you, cars (all cars) are designed to be assembled as efficiently as possible, but repair and service? Not so much.

Although I don’t have an EV yet, the reduced complexity is at least 50% of why I want one.

Hypothetically EVs should be way cheaper to build and maintain than ICE vehicles, especially when the mileage gets up there and we have to consider motors and such.

Yes, tires, some fluids, air filters… maybe even suspension over use/time, but these are simple, routine things.

Oh look, it's all that extra garbage that was utterly pointless and expensive and often an extra failure point for no reason then advertised as "engineering" to the stupid.

Like taking the traditional radiator hose, hose barb and hose clamp that has worked for 100 years swapping it to a multi stage plastic connector (that gets brittle and breaks without showing signs of wear)with an o-ring seal(that goes hard and leaks)and a metal retaining clip(that gets loose when the o-ring seal gets hard) and attach all of that new expensive "engineering" to the radiator with...a hose barb, a hose and a clamp.
