A 1.44" screen is only 240x240 pixels . The text, arrows etc are photoshopped since they are generated in code. The mock up is an easy way to figure out the x,y placement for the code with lines and rectangles. The green fill would change based on DCCD state.    Since its can bus connected it could read the X,Y from the yaw sensor and graph those on the left and bottom edges. individual wheel speed is also on the bus so could have tiny left to right balance for front and rear wheels.  

I had this running a year ago on a small LCD test rig.   Early 2026 have just fount cased 45mm cube with colour display that I can add canbus and 12v power converter inside.  found parts on better than usual sale at aliexpress the parts total is $20+gst plus a few wires, heatshrink etc. have to drill hole in case for power and canbus wiring to get out but it’s very tidy. Could double side tape it to the top or the steering wheel column.   Have  the same 22B image from the TPMS display and some arrows to show diff level. Will upload a screenshot later.    

If you're getting LIDAR from behind you are so entirely and absolutely toast. Basically a pointless scenario for trying to detect, as above laser alerts are usually just ticket notifications and if you get one from behind, quadruply so.   I used to run a relatively high end hardwired detector (well it was high end once upon a time, now it's hopelessly outdated by things like the Unidens) and I didn't even bother installing the rear laser sensor.

Depends on the region but they can stand on the overpasses and tag the back of the car. Their car(sometimes multiple cars lined up) is parked on the side on-ramp so they can quickly get onto the expressway behind people. Some areas they just loop between say north and south bound on two closest exits. As for fast I’ve had one at 108kph.

I'd have liked to mirror mount mine but its just too much of a chonky boy and really fills a chunk of your vision mounted right there...something slimmer like a valentine might work, but I'll take any performance hit for having it up out of the way....I'm not living and dying by this thing  and as everyone knows, any laser alerts are just speed ticket notifications unless you win the lottery and pick up some scatter, so high mount it is.
