Interestingly pigs can't get motion sickness due to the amount of the DAO in their bodies. They naturally produce large amounts and likely my boys both are deficient. Both @stryeyz and I supplement so we don't notice it, but even as a kid I rarely got carsick.
I was through Boise a few times as a kid and the place was MASSIVELY smaller. It has expanded so much in the last 20-30 years it is pretty much one big metroplex.
