Because they work with parts for cars, not carts for pars.
Are you high! flashback to me cry-singing Taylor Swift's "Love Story" in the car on the way over me: Yes
HE'S A LITTLE BUSY TO WORRY ABOUT YOU RIGHT NOW DUMMIES
Because they work on so many levels
They're obsessed with rigid bodies!

None, it is a hardware issue!
A rehearsal.
High maintenance
With parts unknown.
A piebald horse pulling a cart!
Par a guays!
A Pink Car Nation!
