In elementary school, there was a very large hill right next to the school. My mom would always try to drive so fast up the hill that we would fly off the road. I can’t actually remember if she did, or if she just created such magic aroudn driving fast that it felt like we did. Let’s estimate that the hill had a curved top with a radius of 35 meters. How fast would she have to drive (in mph) to fly off the road?
