Maybe I misinterpreted the cause and effect here, but is there a meaningful difference between a Snapchat video with a "speed filter" and a cellphone video of somebody driving fast that includes footage of their car's speedometer? Is any speed gauge likely to make people drive fast, and therefore open to litigation?
Edit:
Here's footage of the Speed Filter in action:

You'll note that neither of them have any special display for reaching fast speeds (IE "incentivizing" driving over the speed limit), and that the first one even says "Don't snap and drive".
