The Really Smart Car

Apparently, my brake bads were pressing real tight on my rotors because there was a problem with the calipers - or somewhere in the system - hoses, etc. Question is - based on the direction gravity is pointing relative to the car's frame of reference, why can't the computer figure out if the load on the engine is reasonable or not and communicate that to the driver - if maintenance is indicated. There should be simple ways of figuring out the actual weight of the car. This should be trivial. This alone might have explained the huge discrepancy between my city and highway mileages. Damn! Come on Honda-san.
