At some point around 2.0g of braking, the rear tyre is completely off the ground and ALL braking is done with the front. In this case, in addition to having released ALL of the rear brake, you'll also want to have your butt scooted off the back with your belly resting on the saddle to keep the rear-tyre down.
Only two nits to pick there; the car has better brakes, the bike just has much less mass.
I really don't think you're going to get much over 1 G on any normal two wheeled vehicle, and that would take conscious technique to keep more weight over the back. Probably less on a wedgie bike than on a motorcycle because the CoG is so much higher (although the pivot point (front axel is also higher...). Cars can go way over 1G streat cars rarely do, but purpose built race cars go way over.
