Because auto-sellers don't want to work both days of the weekend.

Let's say I run a liquor store. I get together and collude with all my liquor store running buddies and pass a law that says liquor stores can't be open after 5pm.

Ta-da, we all get to go home at 5pm. We don't lose any sales to people open after 5pm, because no one is allowed to do that.

And if someone wants alcohol after 5pm, fuck 'em.

Oh yeah, I get that much. Wondering how they got the "either day, but not both" part. Usually those laws are just "no sundays".

No, actually you lose some impulse purchases, in the liquor store case at least. I admit that cars must suffer less from the effect.
