Talking about F1 cars......
How many bike lengths is 17m?An average F1 car can decelerate from 100-0 km/h (62-0 mph) in about 17 metres (55 ft), compared with a 2007 Porsche 911 Turbo which takes 31.4 metres (103 feet).[citation needed] When braking from higher speeds, aerodynamic downforce enables tremendous deceleration: 4.5 g to 5.0 g (44.1 to 49 m/sē), and up to 5.5 g at the high-speed circuits such as the Circuit Gilles Villeneuve (Canadian GP) and the Autodromo Nazionale Monza (Italian GP). This contrasts with 1.0 g to 1.5 g for the best sports cars (the Bugatti Veyron is claimed to be able to brake at 1.3 g). An F1 car can brake from 200 km/h (124 mph) to a complete stop just 2.9 seconds, using only 65 meters (213 ft).[6]

yes, but there's your comparison for engineering. choose any high end race car, pit it against a high end race bike. the cars would kick the bikes' arses.
quick search - Phillip Island - fastest bike lap (Melandri) = 1.30. fastest car lap 1.24 (and that's only in an old Reynard) - 250cc supercarts are 1.32, even the V8 supercars are 1.33

Mikkel, a condescending prick?
Surely not

It doesn't necessarily take a high spec car to get good braking performance. Had a company vehicle once (which we all know are the fastest road cars) it was a little Daewoo hatch that could haul to a stop real quick.
(not every corner or the brakes cook)
It also needed it's first brake pad change at 27thou and new disks at 40thou then pads again at 75thou when I handed it on.

Off the mikkle bashing and back to the topic, some interesting figures, obviously not DIRECTLY comparable but worth a gander.
http://brianrpatterson.blogspot.com/...-are-they.html
Bike braking tests for some bikes with ABS ranged from 37.4m (BMW R1200R) to 49.1 (Yamaha FJR 1300)
http://www.wheels.ca/article/32604
Average small car tests, braking distancees ranged from 47.9 metres (Ford Focus SE) to 41.5 metres (Mitsi Lancer GTS)

This site puts braking performance of an older Honda NSX at 134 feet (just under 40 meters)

Nooo ...... don't give me links! I prefer artistic licence interpretations that mislead and confuse, way more entertaining!
.... err sorry I'll go looksee now.

And here is the science bit explained with a bit more of a practical eye, makes sense to me
Truck, Scooter Stopping Distance
2/15/2004
name Soman P.

age 40s
Question - A truck and a scooter, both are moving in the same
direction with same velocity. Which vehicle will come to rest first
when the brakes are applied simultaneously?
-----------------
Soman P.,
In an IDEAL situation, provided both vehicles had the same coefficient of friction between
wheels and ground, both would stop in the same length of time. If the truck were 1000 times
the mass of the scooter, the truck would have 1000 times the momentum and 1000 times the
braking force. For constant force, (momentum change)=(force)x(time). The same time works
for both situations.
In a REAL situation, the truck takes much longer to stop. This is because the truck's brakes
cannot exert enough force to keep the wheels from turning. For a scooter, the brakes freeze
the wheels in place. The scooter slides to a halt. For a truck, the brakes only slow the
wheels down. There are several reasons for this. First, the force produced by locking the
brakes in place would damage both the axles and the wheels enough to be dangerous. Second,
the wheels would stop the truck but not the load in the trailer. The material would continue
moving forward, crashing into the front panel of the trailer and possibly breaking through.
This too would be very dangerous. Large trucks and semis are designed to stop slowly.

In the riders seat
In the real world I've seen many a truck completely lock the brakes up and flat spot tyres in emergency stops
"If you can make black marks on a straight from the time you turn out of a corner until the braking point of the next turn, then you have enough power."
for a physics professor, Dr. Ken Mellendorf uses some pretty emotive language.
Night rider
Which confirms what has been said again and again. A bike (BMW R1200R) can out brake a car (Mitsi lancer GTS). A car (Mitsi Lancer GTS) can out brake a bike (Yamaha FJR 1300).
It all comes down to rider/driver ability, coefficient of friction of the tyre/road surface and ability of the brake pads/disks to absorb and disipate energy.

Damn right!
and lean angle too...
I have had my head hit the rimutaka hill pretty hard trying to scrub of speed in a real hurry!

Yeah, come to think of it the load probably aint going to push thu the front of the trailer either, I would guess that the trailer would Jackknife around as a result of the continued motion of its loada and weight.
Academics aye..
