Going by the logic that a remake often leads to the original being easier to get ahold of, Japanese corporate espionage thriller Black Test Car seems like a pretty good candidate. It would probably have to be a relatively loose remake, but the idea of a bunch of people from competing companies spying on each other to get the drop on an upcoming product launch could be pretty entertaining and it'd be possible to find the original too.

For those who aren't familiar with it, Taiho Shichauzou/You're Under Arrest! is an outstanding animated drama series from Japan, featuring a team of traffic cops and their unusual encounters on Japan's highway system and city streets. The occasional guest vehicles include an 80s Lancia rally car vs a motorcycle cop in a street-clearing monsoon, a seriously souped up Mini Cooper whose driver not only makes a mockery of the police's superlative skills, his secret identity will make you cackle with glee upon its revelation, and the only surviving Emily in repose at a city park.
The central duo's Honda Today is fully equipped with all the top performance mods of the day including nitrous for a brief boost of ludicrous power, an upgraded Motocompo to run down the perpetrators when they take paths even the diminutive kei car cannot traverse, and their motorcycle riding counterpart who can provide a sustained level of high speed pursuit when their tiny terror (terrier?) simply runs out of breath. Characters at the station include the obligatory meganekko (aka girl with glasses), a ne'er-do-well student who straightens up and joins the force, and – I'm just going to refer to Aoi . . . as Aoi.
The series was rerun in a live action format in the 90s, but there are several multiple episode stories which would provide more than enough fare for a busy live action feature film, including the detection, tracking and shutting down of an international exotic vehicle theft and trafficking ring whose members enjoy playing dirty pool, up to and including shooting members of the force and kidnapping one.
The busting up and taking down of the perpetrators in the final episode is a city and highway chase of epic proportions which finally ends with a container truck on its side filled with evidence, the perpetrators dazedly picking themselves up from the street, and the Taiho team surrounding them while Natsumi walks up, whips out her ticket book, and starts listing all the minor moving violations which were committed during the final chase.
"Waitaminute; you're just traffic cops?"
"Yes; the national police are right behind us and will deal with your real crimes."
"AAAAHHHH!!!!"

Screw car movies. I'm feeling very contrary today. It would be nice to lampoon the current cyclyng culture as a bunch of human pharmacological experiments. They're pretty much doing that themselves, but in a post Lance Armstrong world we need a scrappy blue collar champion to kick all their asses, right? I'm envisioning a Zombie element, where toxic waste gets into the EPO supply and the competitors all start mutating.
