Well, GPS has a good point and a bad point but anywhere you put it its just put you on the spot whether you are working or just passing time. There are many ways to justify work but electronics cannot change the actual check whether or not a mechanic does his job or not. To me, GPS users are persons not trusting or does not have proper control on their operation. Service is about connecting to people and building relationships and I don't think that GPS can improve that. In the end it is what we can do for our company that matters. If the company treats us well then there is no need for GPS, only proper monitoring based on loyalty.
