Couple of reasons.
1. User forgets to start tracking mode on there tracking device from day to day.
2. If using a spot device positions are only captured and sent every 10 mins, you can cover a fair bit of ground in 10 mins and thus a straight line appears.
3. If a user does a trip and comes
home and does not save/archive the trip tracking files and some time down the track starts tracking again it wil just be appended to the older log so this may create a straight line.
There are no system reasons for a straight line and the mobile phone and PC software options have the ability to do constant tracking done to about 30 metres (thus no straight lines provided it is running of course, and dependant on how much data plan you have).
The SPOT cannot do more than 10 mins and it could be up to 20 mins dependant on GPS and transmission satellite coverage.
Hope this answers your questions. Keep asking if you need more information.
