That's not my experience at all - cars stop a lot faster than both motorcyclists and certainly than plain cyclists (I cycle almost every day multiple times).
The thing is, in a car you can basically be unprepared, then mash the brakes when somethings wrong. It's possible that'll cause you to lose control, but in general an emergencey stop whether controlled or not will stop the vehicle very quickly without causing any direct injury.
By contrast, on a (motor)bike if you mash the brakes you'll slip or even tumble head over heels. You're not wearing a seatbelt; and furthermore your vehicle loses control a lot less gracefully.
If you're prepared, it's a different story since you can rearrange your center of mass, and get a good grip beforehand, but in an accident situation... a car stops much more quickly.
