If somebody was in a hurry, they'd just gallop around them. The pace was slower than what we know. People could see the whites of their fellow Wolfeboroughian's eyes. Not so today. If we do, we get an earful of horns and screaches.
Travel is just too fast to even see people's heads, let alone their eyes.
But we who drive have a subtle and clever way of connecting with people on the road. It's superficial, but it fills a void. The index finger of one hand raises from the wheel. No response, deadpan face, not even a side-glance. There are lots of variations on these basics.
