Is a laterally hemispherical vehicle practical? Absolutely not. For anything that fits in a car lane, you would not be able to do anything with the outer quarter on each side, half of the width, so would it be worth increasing the frontal area? No, but it would completely eliminate vortices, or so I read.
Round is good, where possible.
