Invent the wheel.

Have you ever tried to pull or push a wheeled cart up a large hill? Wheels are not super useful on steep terrain or unbroken ground and are often a liability without a bullet proof brake to stop it from trying to roll away when you stop. If the land isn't super rough or steep then wheels are great, but when it is you are going to have to work twice as hard.

And be stuck only ever going where someone else has invented the road for you.

Big same. Now need big wheel.

Good luck using a wheel in uneven terrain. Why would you even leave a comment like this?
