Given the data that can be extracted from GPX files, and the plans to create the VehManPi (so data will constantly be reported);
A killer feature may well be the ability to generate a report for an insurance company in the event of a claim.
If you have an accident and the other driver claims it was your fault, it'd be awesome to be able to provide a (verifiable) report of the journey including speed, accel/decel stats etc.
If we can think of a way to do it (bearing in mind times are UTC) it'd also be pretty cool if we could provide an additional section focusing on the minutes just before the accident.
Depending on the nature of the accident we could probably tell when it was from the journey log, but might be better to have the user provide the rough time.
The report would need to detail the entire journey (as the other driver might claim you'd been driving like a pillock 20 minutes before).
The following charts (existing and to implement) should be embedded into the report
- Accel/Decel chart
Speed vs Elevation chart (possibly)
- Journey Speed Chart
- Journey Map
The stats generated for the journey should also be included.
