I suppose it would depend on the driver. I know a few people I could fingerprint with the lousy IMU built into my ears with no computer analysis - some go constantly from the white line to the yellow line and back, some don't realize that the accelerator works at input levels below 10%, some second-guess the automatic transmission at every shift...but many drive, well, normally. Regarding the mouse or keyboard inputs discussed in this thread, there are a few hunt-and-peckers or over-correctors who would similarly be found. I don't think it's that impressive to get a few drivers out of a sample, they likely have detectable quirks.
