that sounds fun.
Dahlia was hot rodding it in her 12v jeep. She's top of the size range, but half the weight max, when alone, so it was really cruising. 5mph seems fast when you're 6 and driving. I was surprised at the 'hill' climbing in the snow, with plastic 'tires'. I'm going to figure out some traction aid. I'm thinking of construction adhesive in a sine-wave pattern, so it doesn't thump, thump, thump, thump on gravel and pavement.
