For ages now we've been wondering why we manage to makeup so much time when using shortest route on our Tom Tom.
Sticking to the speed limits we still manage to reduce our travelling time by 20 to 30%.
We wondered why that didn't occur on Motorways?
Whilst tinkering with the Tom Tom this evening, planning our next route through Europe we ran a demo.
We found on the UK section, it assumed 51 mph on single and dual carriageways BUT 75mph on motorways (the same as in Europe)
So think carefully when your planning your next trip using the Tom Tom ,the quickest route is not always the quickest, as it assumes your going to break the speed limit if using the motorway.
