Wow I must say. Yes, it is a simpler system as it does not need separate extra parts, i.e. the pressure sensors as it uses the ABS wheel speed sensors for the speed monitoring on each wheel. This system can only tell you if one or two wheels are getting low as it compares the wheel speeds.
Wonder how it works for a housewife who don't know that a sudden temperature drop of say 30 C can severely under inflate all tires. This system would have hard time to know all tires are low.

I could buy that excuse if the Canadian cars said "Start Parktronic, eh?" on the screen... Oooh...how do we change the text on the instrument cluster? This could lead to evil things.

Not in the F30/31- 3 Series; they have the same TPMS as MB for Canadian W2014/5 and W211/212. Perhaps some of the higher end models use the US style electronic sensors for each wheel ?

No, even my S-Class doesn't have the American style tire monitoring system. When the system alerts me to check tire pressure, I have to pull over and check each tire manually with a gauge.

How about International Falls, MN? One of the coldest places still livable in the U.S.
I think the reason for the two different TPMS between U.S. and Canada is that the government in Canada has not come up with the law requiring the real pressure monitoring in the tires yet. But it is coming I believe...

My understanding of the US TPMS requirements are that the car notify the driver that there may be a problem, nothing more. I've seen US-spec cars which only have a single idiot light, making the driver guess: 1) What the heck does that symbol mean, 2) which tire might be to blame.
My 2004 M45 shows individual pressures, a coworker's 2008 Chrysler only had a single light. I've also driven a 2012 VW Passat which only had a single indicator.

Sorry for continuing this OT discussion (relative to the OP) but I just had to comment. My '13 X3 had TMPS with individual sensors and the display that showed by color (grn, yel red) the offending low tire, but although the sensors were capable of measuring and transmitting individual pressure numerics, the display would not show those. However, I could purchase an 'Enet' cable to connect to the OBDII port and use special software (easily obtained on various forums) to program the numerics to be visible. My guess is that they dumbed it down so as not to confuse drivers with numbers and use easily understandable traffic light colors instead. They could probably have used both methods (colors + numerics) with the 'flip of a bit'. How silly.
