Wife just told me that our 16-yr old has been flipping on the parking brake while she's driving. Apparently it's "happened" a couple times.
(Don't ask me why....)

Is it bad for the car?

You should see a red "park" illuminated on the top part of your dashboard if parking brake is engaged. I think the system should prevent that above certain speed? Otherwise you can drift your XC90.

Parking brake is released when car starts moving. Just try it from standstill you should see it happen.

More importantly, how about he / she just stops flipping on the parking brake while the car is being driven?

My parents would've slapped me over the head and then kicked me out of the car if I did that when I was younger.

Well as advised from the s60 manual moons ago, you risk reduced tire life, potential loss of control of vechical, and / or brake life, if used while in motion.

In the XC90 manual it says that you have to pull it and hold it to use it as an emergency brake, so doesn't do anything if you just flip it while driving (as expected, being a switch)

As it was rolling down the road, yup mine too!

I really want to know why she was flipping it on... Just curious.
Perhaps disbelief when friends told her about electronic e-brake switches and trying to see if there’s still a hope :D

+1 Exactly what I would have done to any of my kids if they did that. Also, it can damage you E brake.

Yes, you actually have to hold the parking brake up for it to apply while moving and as soon as you release it, it stops applying. She'd know if it was applied as well, it's pretty loud and you can feel the rear wheels grab.

That would be great!

I'd slap him too if I were driving

Supposedly the car lurched. I wasn't around.

As a car guy I'd have to say I'd sort of be proud of my kid for trying handbrake turns (if in fact that's what she was doing). I'd also be pissed for doing so on the wrong type of car...high profile, rollover risk, etc.

Pulling the parking brake on the XC90 actuates the rear brake calipers. So from a damage perspective it's akin to slamming on the rear brakes only. Hard on pads/rotors and rear suspension, flat spot the rear tires, etc are the results. My main concern would be rollover risk or hitting something if they get sideways with the rears locked up.

Mom was driving, kid playing with the controls.

Why do kids drink/smoke even when they're not "supposed to"? Just being kids ;-) (and mom not being very attentive)

I have a 2 year old that plays with the buttons. I’m hoping that by the time he is 16, we have moved beyond this
Yeah I would hope so too! Well he'll have a license in a couple months, after that he's on his own! (LOL)

Sounds like it applied and stopped when he let go. I wouldn't recommend doing it on a daily basis, but it shouldn't cause any issues. Always good to know your safety systems work as intended.

Wow that’s really dangerous! As the driver, I’m sure it was unexpected for your wife and being unplanned by the driver could have created a bad situation. I thought your kid was the one behind the wheel and flipping the switch while driving, not that she was messing with rear brakes while not also in control of the car.

I misunderstood...I thought you were talking about a teen driver taking the car out and pulling the parking brake button for fun.
