    I was driving about 55MPH on a frontage road today and a car with an out of state licnese plate suddenly cut in front of me going 30MPH. There is plenty of room for her to speed up but she slowed down.

    I slammed on the brakes. This is the first time I enaged the ABS on this car. It was dry and on a well paved road. I know the ABS was on since the skid light started flashing and I could hear the tires doing the intermitten lock up thing. However, I did not feel the brake pedal pulsing like I was used to with other cars.

    The story had a happy ending. The car stopped well, and I stopped in time and honked and then she made a lane change and caused someone else to slam on the brakes too. The other driver stopped in time too but flipped her off.

    Does the Prius' brake pedal not pulse under ABS braking?

    That is correct; as long as the braking system is working normally, the brake pedal feel is simulated by the computer, and not directly linked by hydraulics. As such, there is no pulsing feel in the pedal.

    Early ABS used to clearly pulse. On my 1997 Camry, the pulse was even faster, so it felt like gritty sand on the disc brakes. I haven't activated the ABS yet on my Prius, but I bet the latest version is even more indiscernable to the driver.

    I had the "bad" fortune engaging ABS in the last three years at least 5 times on the GenIII and about 3 times on the previous GenII .. I can confirm it is different from other cars I drove ... but you can feel the difference from normal breaking. But not that much on the break pedal but the way car behaves. It feels between skidding and just slowing down. And will not stop you actually skidding sideways/fishtailing which I also experienced but helps a LOT to correct it. I think without this ABS I would have lost the car easily.

    Yes, ABS has saved my bacon multiple times, although it has its limitations.

    Wouldn't VSC kick in if the car starts to fishtail?

    I am not sure what VSC. But one of my situation was such that I actually was in a turn when I had break hard to avoid the idiots changing lane. Actually going straight when all three lanes were slightly turning left. I had maybe a half a lane left on the right and the car started to skid to the right but had enough room to actually counter steer which got me back straight and saved the day but if there were a curb much closer boy I may even flip the car ... (it happened at about 45-50 MPH ). The breaks are not the best ever I drove but pretty OK with one person in the car only.

    Yes, the VSC should kick in, and you will really notice it take over. Also, the VSC light starts blinking and you hear an audible warning. It gets your attention, almost as much as the situation that got you to the point where VSC kicks in!

    Exactly, I think the VSC flashing light and warning beep distracts the driver from a dangerous situation. Also, I've found that the poor traction of the low rolling resistance tires to be a greater limitation than the braking system, which seems to be excellent.

    OH so maybe it was not "my brilliant" reaction to the situation which saved me :)

    That question I cannot answer! For me, being rather slow-footed, the car reacted and responded before I could figure out what to do.

    I had a couple of those in dry weather. Pleasantly surprised by short stopping.
    I'm sure wet will not be as good.
