Why don't all cars have mudguards?

Don't you need to get the water away from your tyres rather than diverting it and dropping it back under the tyre?

Because car buyers don't want them.

Probably affects the aerodynamics and thus the emissions or miles per charge spec for the vehicle.

What? You don't want naked girl mudflaps?

I suppose the Yosemite Sam mud flaps aren't culturally sensitive enough.

EEK a man with a gun, two guns. I think they are assault weapons. Save the children!

Did someone say mud flops?

They look like crap, they create drag, they fray and tatter, etc.....

And the thing about stopping rust doesn't ring true. Doesn't some mud get stuck between the flap and the vehicle? Cindy had the best answer.

If you go to Iran you can burka girl mudflaps.

I don't have a picture because they don't allow pictures to be taken.

Mudguards are always on the trailing/rear edge of the wheel arch so any water that is flung off the tyre runs down the mudguard onto the road

In answer to the Commander's original question, I imagine lack of mudguards is simply a cost-saving thing on cheaper cars.

If you must get trolled by Kinsey, take it to a car group.

urc dropped.

You've given me a reason to want mudflaps. Just to trigger the lefties in Ann Arbor.

I thought only pre-war cars had mudguards. More modern ones have wings.

I think the modern meaning of "mudguard" when applied to a car/lorry/bus, as opposed to a bicycle or motorbike, is the flap below the wheel arch which extends towards the road as a means of channelling muddy water onto the road so it doesn't spray around and get onto the windscreens of cars behind.

The Lotus 7 had mudguards

Those are mud-flaps.

I think that the OP meant a moulded/pressed body part which fits inside the wheel arch above the wheel (and is perhaps removable and replaceable). Its job is to prevent water and mud from being thrown around inside the wing and perhaps via bulkhead gaps into the headlights and engine compartment.

It's often hard to tell what the OP means.

Your version of "mudguard" (wheel well liners) wouldn't do much to "stop water sprayed up reducing visibility behind you" as noted by the OP.

In fact, they probably increase the spray since the water is going back down ono the road and picked up by the tires.

...almost anything. Its 'commander' Kinsey. I think he just likes the sound of his own voice
