Hell yes..... I even did it when I had the Company vehicle, sod em....Then after one visit I got a shout asking why I had been in a particular area when I was supposed to be somewhere else, lucky for me they had not twigged I was off sick....lol
Turned out the vehicle had GPS Tracking and I never knew.
Not to be beaten I bought a gizmo to block the Sat Nav/GPS signals....
Start vehicle at home, use the blocker and then go where I want, all it showed them was my vehicle running, no idea that I had moved at all.
Used it for ages, even for shopping trips at weekends.....lol
Oh Joy...
