Ok, ok, I'm going to bring the bickering to an end.
I propose highway-flyer, interstate-flyer, bonneville-salt-flat-flyer and really-long-straight-downhill-country-road-flyer. These are, of course, all used in the noun form.
If we are talking about it in verb form then it should be highway-flier, interstate-flier, bonneville-salt-flat-flier and really-long-straight-downhill-country-road-flier.
Flyer, flier, pants on fire. Or is it fyer.
