So if you threw some homemade chaff(bunch of aluminum strips) out the window do you think that would cause cars with radar based automatic braking systems behind you to go nuts?
Future Bond vehicle feature?

Out your CAR window while driving? Why would you dump debris/potential projectiles on the roadway? Real life isn't a Bond movie.

Yes, it's just a thought experiment...

On my daughter's 2019 Honda CR-V, if the snow or heavy rain builds up on the grille in front of the radar sensor, all sorts of bells and whistles go off indicating a system problem with the radar based systems. (Common known issue, with Hondas at least)

No apparent issue with braking, but then she does not use the adaptive cruise control.

So I imagine if the chaff hit and stuck to the grille/sensor, the same would happen. Just prior to a build up, maybe something else would happen depending on the density of the chaff "cloud".

Yeah snow/ice buildup causes them to deactivate. Basically just like military chaff I'm thinking it would interpret that as a big return and brake without making contact.

I was thinking about would the automatic braking engage if an object flew off the roof of a car or bed of a pickup like a sheet of plywood or mattress for example. Some people see such an object and freeze with fear, their foot never reaching for the brake pedal. For more northern regions, would it engage if a sheet of ice flew off the roof of a vehicle? Both of these situations have happened on the roads and so are very real possibilities

I'm leaning more toward having a couple boxes of caltrops in trays I could drop from my rear bumper to solve the problem of tailgaters!

Only flaw is I drive the same roads every day... LOL

My truck has that collision avoidance thing, it's activated a couple of times when driving down steep, turning driveways when there's like a car or wall fairly close in front. Seems it gets confused due to the angle of approach. It's never actually hit the brakes, just scares the pants off us. I DO NOT need my car driving for me.
