Speed-detecting road spikes are just the beginning. After some consideration, I've decided that the first few vehicles affected by the spikes would be amusing, but subsequent ones would be a pain. One can call the towing company only so many times before it gets old.

My new invention: electrically varying road surfaces. It gets very sticky when an oncoming vehicle travels too quickly. Many drivers will smack their foreheads against the steering column. A few may spin out and hit a sign post. Most will just stop or slow down dramatically. This would be very amusing without having to call the towing company.

On the plus side, there appear to be fewer panels tonight. And the cones along the main road are gone.
