A DEQNA ethernet controller card can measure to an accuracy of 100ns which is around 20m at the speed of light. Shockwave velocities in the ground are in the order of 1000 to 10000 m/s or 1 to 10 m/ms so sampling at 1ms intervals

I agree with you that acidity is the main cause of enamel erosion. The correlation between beverage acidity and tooth decay is such that I think we should highly discourage children from drinking any carbonated or acidified drink . I disagr

Definitely cheating, it's not autopilot. It is just updating your co-ordinates every 500ms on a straight line. I would like to see a real autopilot written in javascript that you can paste into the console.
