Highway Road Racing is an endless traffic dodger in 3D: your car accelerates continuously down a busy motorway and you weave between vehicles, with the density and speed rising the longer you last.
It's the purest form of the format — no laps, no rivals, no upgrades to distract from the fact that you're being asked to react faster than is comfortable.
No — it's endless. The traffic gets denser and the speed higher until you crash, and distance is the score.
Look far ahead rather than at the car in front, and commit to lane changes early. At high speed, reacting to what's immediately ahead is already too late.
Yes — it runs in the browser with nothing to install.
