Testing a Lego car against longer and longer gaps that it needs to drive over. Gradually improving the car until it becomes a capable gap crossing/bridging vehicle. Things you need to consider: wheel diameter, wheel count, 8WD, wheel position, center of mass, frame length, frame strength, moving mass, weight reduction. Enjoy!

Base rules for all builds:
-max length 1 meter
-no steering (to simplify the builds)
-only Lego parts used
