Okay, here are my answers to this puzzle:

Car-
#1 & #2: The body of the cars and their numbers are glued to the background.
#3: Two tiny axels hold the body to the background.
#4: The car is held in place by an invisible circle that's stuck on the front of the car and glued to the background. Also, the wheel's friction values are set to zero.
#5: There are two boxes under the wheels of the car that are on layer-J which is not selected, and therefore they are not visible.
#6: The car has two extra FAKE wheels and axels that prevent the car from moving.
#7: The car is "hanging" by two invisible circles above it, which are glued to the background.
#8: There is a very thin, invisible rope or chain stuck to the rear of the car, keeping it from moving forward. Also, the wheels friction values are set to zero.

How'd I do?

Excellent. Best answers so far.

On car 7 you can identify the thruster by using the box tool to select the car and wheels and then choosing Selection>Select to identify the component you would not expect to be part of the car.

Solutions by car number:
1. Tiny fixjoint fixes car body to background.
2. Car body glued to background.
3. Two tiny axles hold the body to the background.
4. Sky colored circle glued to background in front of car. Zero wheel friction.
5. The car is up on two sky colored J layer blocks. J layer is turned off.
6. Braked and depied original wheels. Added zero friction, slightly smaller wheels over original wheels.
7. Car forced up against two sky colored J layer glued to background circles by tiny thruster. Zero wheel friction.
8. Thin spring attaches rear of car to background. Zero wheel friction.

One-man contest, huh.

I guess so. You snooze you lose.

I'm one of best engineers and was one of best thyme-scriptres here. Go duck yourself.

I disagree, you still are one of the best thyme scripters. At any rate, don't feel too bad since the scene was intended to be a puzzle and not a contest. You were the first to call it a contest and I figured that was my big chance to make a snide remark.

P.S. Just to be clear, I do agree that you are one of the best engineers in Algodoo.

This is an excellent puzzle scene, and I hope you will create more of them! It was very challenging. I probably jumped in a little too quickly, so, next time you post a puzzle I'll step back and give others a chance to solve it.

Nice work!
