I have a GT with tech package, so AFAIK, I should have smart city brake support. I have it turned on in the settings menu, but I don't know if its working. In bumper to bumper traffic, I can get really close to the car in front of me without any feeling of auto braking, but I'm thinking maybe the car knows when I have my foot on brake and it doesn't kick in. How do I test it to know if it is actually working without crashing into something if it isn't?
Smart City Brake Support - How do I know if its working?

This is what is mentioned in FSM for calibration steps. Seemingly not much harm running into that.
1. To make the simple reflector, overlap three pieces of commercially available aluminum foil and adhere them to a plastic plate or piece of cardboard with a length of 50 cm or more on one side.
If two or fewer pieces of aluminum foil are used, near-infrared reflection may weaken and the M-MDS will be unable to measure the correct distance.
A reflective material or material which facilitates near-infrared light reflection can be substituted for the aluminum foil.

So drive into a big cardboard box with aluminum foil on it?

We've seen that video before but that won't work on Mazda's Smart City Brake Support system. SCBS is not a Pedestrian Avoidance system offered by Volvo and Toyota. It has to be a metal object to trigger the brake as evidenced by using aluminum foil for testing.

You're no fun.
That said...how exactly is this good or okay with all of the synthetics used in vehicles like the viper? It could end bad

Ha, my wife has been saying that for many years! But I was trying to point out that Mazda's Smart City Brake Support (SCBS) and Smart Brake Support (SBS) are designed only for detecting vehicles, not human beings. I'm not sure how effective Mazda's systems detecting a Corvette with carbon-fiber body. Heck, even a system designed detecting human is not 100% effective:

If you can find one, drive up to an automatic parking barrier or toll booth barrier at a steady low speed... I've had to change my style of driving since getting my CX5 with this technology as the car very often doesn't like the sudden movement of the barrier while driving at it with the CX5. Stops dead, alarms going off and me red faced...
My SCBS has engaged twice. Once at a parking/barrier arm leaving a parking garage, and again pulling into a parking space in the parking garage. I must have pulled into the parking space too fast - there was a metal sign hanging from a short post at the end of the parking spot (think that and the speed at which I pulled in is what triggered the SCBS)
Oh it works
We put 2 huge bags of packing peanuts in the parking lot of my job. First I drove around 15 MPH and it stopped nicely, 2nd test I got up to 20 and it slammed my brakes on HARD and my CX 5 was actually touching the bags, third test, went over 20 and didn't stop at all. For the hell of it, we even tried it while I backed up, didn't think that would work, but we were having so much fun doing the testing

I'm not sure why so many folks question whether or not its working... but anyway...
I have some low hanging branches over part my driveway. I've had them set off the SCBS system before in moderate wind... completely startling my poor dog riding along in the back seat. (The branches can sway down to be in the line of sight of the sensors). So it doesn't necessarily need to be metallic in nature to be picked up by the sensors.

I think it actually doesn't engage at faster than 20 by design. Maybe because occasional false positives at higher speeds have worse consequences.

Yeah Smart City Brake Support (SCBS) only works between the speed of 3~18 mph. It's Smart Brake Support (SBS), if so equipped, will be activated at the speed higher than 15 mph for similar functionality. BTW, we have only Smart City Brake Support Forward system in the US, whereas other regions are also getting Smart City Brake Support Reverse (SCBC F/R) which works while the car is going reverse.

According to CX-5 manual it does look like the laser sensor does pick up greens & the like:
(SCBS section) When driving off-road in areas where there is grass or forage, it is recommended that the Smart City Brake Support (SCBS) system be turned off.
While SCBS only uses the windshield mounted laser sensor, SBS uses both this Lidar unit and the radar sensor mounted behind the front grille/Mazda emblem (and of course the camera as well, also mounted on the windshield).

I just came from my local dealer and I asked them about this they said:
2-18 mph and if you do not touch the brake it will activate. If your foot is off the gas, off the brake, it will activate if you are on the gas it will activate. If your touching the break, the system thinks you are aware and in control of the situation so it does not activate.
This is for the smart city brake. Not the radar cruse control; The one thing I forgot to ask is how far off the vehicle in front of you will it activate.
Hope this helps.

Wait where are you located? Sorry on my phone and don't see if you have a location posted. So your reverse system worked in reverse for the scbs? I know the cx5 can do it but not sure if US one does it.
