Bowser jr used his paintbrush from Sunshine and turned himself into sonic.

“Sonic’s fast, why does he has to use a car in the racing games?”
This is why.

Seeing Sonic overlap everyone, that put the biggest smile on my face. It looks so natural!

And this is why Sonic drives a car in his racing games: to make it fair.

1:23 Sonic riding on air

"Everybody's super mario racing"

Mario and Luigi: running in a race
Sonic: VRUMMMM Hey there!

"That's not even my full speed."

I like how Sonic surfs on an invisible board when finishing the race.

I SEARCHED this and it said one minute ago and so I clicked.

I love how Sonic has combination voice of all 3 of his big ones: Ryan, Jason and Roger.

Sonic was moving so fast that not even the rubberband AI was able to catch up with him. They did get pretty close in Toad Factory, however.

Take notes Sega, Sonic clearly doesn’t need a car to race.
Edit: So I wrote this comment 3 years and it’s still getting replies for some reason? But I’ve definitely changed my opinion since then, I think Sonic racing in a car is fine because as several people have pointed out it, he’d easily win without one. Still, I think a racing game where Sonic runs on foot could be really cool (Sonic R but done right)

50cc
Sonic:Too slow
150cc
Sonic:too SLOW
250cc
Sonic:too lazy
500cc
Sonic:not a real challenge
999cc
Sonic:alright!!!

This= brilliant
Why isn’t this real?

For some reason Sonic running on 200cc is satisfying

3:11 Sonic uses his invisible hover board

2:00 in this moment I received an add, when the 1 appeared

Damn, once Luigi Circuit started up, he was GONE! Nobody could catch up to Sonic!

I fear no man but that thing (sonic in Mario kart) it scares me!
