Jackwagon

A JackWagon Rogue isn't specialized in anything, except being very different from everything else.

Everything's A Weapon!

Starting at 3rd level, anything you have can be used as a weapon (although ineffectively) and you can add your proficiency bonus to improvised weapons, and deal damage at certain levels with them:

1d4 at 3rd level

1d6 at 6th level

1d8 at 11th level

1d10 at 17th level

Hop on the Jack Wagon!

When in battle, any vehicle you're driving has +20ft of movement speed. Additionally, you have advantage to any stunts you do with the vehicle

Bop 'Em!

Whenever an enemy makes an AoO against you and misses, you can make a free attack against them

Jokes on you!

Once per long rest, whenever an effect is put on you, you can choose to fail the effect save, and have it put on the creature who gave it to you instead

Laughable Luck

Each time a creature makes a save or check that you can see, you can choose to make them either succeed or fail up to 4 times per long rest
