Ah, but the SatNav part could equally show that you were doing a consistent 29.9mph when the taxi drove into you.
It could, but that’s irrelevant. All it needs to show is that the taxi did actually drive into me. Everything else is just muddying the waters. (I was actually doing about 12mph, fwiw)
Cheap eBay dashcam FTW. Fit and forget, you can guarantee that the time someone drives into you will be the time that you forgot to pop your phone on the cradle and open the app…
Something like this is what I’d reccomend; it produces the same quality video as mine, but it’s much more subtle than mine. A friend of mine has one so I’ve seen it in use first hand. £41 to your door (I have no vested interests 😆 )
