To be honest
My experience of sat nav's is that they do this all by themselves from time to time, without all that tedious mucking about with Pi's.
I have been told I am driving in Brussels while driving in the UK countryside. I have seen it stall (usually just before a complex junction) and resurface just in time to tell you to do a U turn. In some cases almost maliciously sending me down a road only to come back past it later.
Anyone who trusts their computer blindly will be the one parked on the railway track...
