I can't help but think that this is another example of technology for technology sake.
It has some merit, however most of these systems have a problem when dust builds up and they give false readings.
You would think that checking Brake pad wear was a complex task and could only be done effectively by sensors (not)

Technology, when it works well we love it, when it doesn't we hate it. Sometimes I wonder if we really need it for everything.
