Or do so with more acceleration; for which I don't know if his bike was topping out laden down with two people.
And regarding the two people, one, you're an idiot for not wearing proper safety gear, two, you're an inconsiderate ass for not having her wearing proper safety gear, and three, you are a senseless cockpouch for risking another's life. Risking your own is just fine. Risking another's...? No.
