Just had a trip down to Bracknell. Down the M40, off a J4 and down to the M4. I don't know if you know it as you come off the M40 and go round to the link road. Full of traffic.
Well, according to the track log of my 2599, as I was approaching the lights to turn onto the slip road, for 1 second I did 137 mph. The 7 seconds before that I was doing 2.4 mph and the 1 second after I was doing 15mph. Amazing acceleration and braking in my 2 litre diesel car. I wonder what G force I was pulling - and all that in the 8:53am traffic......

Judging by that log it reckons you covered 202 feet which calculated the speed. All I can assume is that you had a temporary GPS glitch. Bridge, tunnel of trees, etc.
Shame you missed Silverstone you could have entered _________________ Satnav:

yes. I looked at the trip log on the map and a few points before that, it had me going backwards down the slip road (which I didn't do). So, it got a bit confused...... |

I'd get this thread deleted before you get your collar felt by the boys in blue, 137 will probably get you an instant ban _________________ Galaxy Note 4 / TomTom GO : CamerAlert : CoPilot |

Do they have any evidence that this was from his car?

And looking at the rest of the data, it's obviously in error and no doubt even more obvious if full access to the lat/lon were available. |

Those figures even put the Tesla S model to shame with it's 0 to 60 time of under 3 seconds. _________________ Satnav:

And as for 2.4 to 137 and back to 15 MPH in 223 ft. That's fairly good. |
