Wheels were invented in.... uhhh...
The point is you are a fucking idiot.

because they haven't been discontinued

What exactly makes rotary engines so bad? The design seems so much fucking simpler than pistons, I honestly can't conceive what can even go wrong with a rotating triangle.

>>16158104
like over 70 things can go wrong
plus imagine looking like a try hard faggot at gas stations having to pour oil in your gas tank just so your engine doesn't melt.
rotaries lol!!!

No one does

I like rotaries because they shoot flames so easy but this is wrong. They straight up have like 3x more seals than piston engines that can go bad. More points of failure means more chance of failure.

Fucking tard

Who invented the wheel?

>>16159316
>"The first evidence of wheeled vehicles appears in the second half of the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), so the question of which culture originally invented the wheeled vehicle is still unsolved"

>rotary has more points of failure than a piston engine
three seals per rotor vs like four plus rings per piston
lets not bring all the other 'points of failure' into discussion either
