Start a race on the TV. Everybody goes to the address (or scans the code) and types the 4 letters. Pick a car. Up to 4 people; computer cars fill the grid to 8. Two can play on the TV's keyboard.
The car always drives. You just steer: drag your thumb left and right on the wheel, or turn on TILT and tip the phone. Two laps around downtown, a figure 8, so you cross everybody in the middle. Ram them.
Bumpers, doors, the hood, the mirrors. Walls take them off, other cars take them off, the dirt road in the park shakes them off. You can always drive. It just gets worse at steering.
GRAB swings a claw at the car next to you and steals a piece of it (it's yours now, bolted on). ITEM uses what you picked up. HOSE (hold it) sprays the car ahead: they can't see, and they slide. WIPERS clean your screen. HORN scares people out of the way. Mostly.
Water, mud from the dirt road, and the red stuff from the people you hit. It piles up. Wipe it.
Drive through the price tags at the garage sale: a dog leash (four dogs pull you), a tow leash, the crane claw, a lasso, the reacher grabber, a fire hydrant.
Hit somebody and they hang on. A lot of people make you slow. Somebody can steal them with the reacher grabber.
The HIT WOMEN 4 HIRE signs. Drive through and they climb on your roof and stand there like chrome statues. They make you heavy (good for ramming) and they grab at whoever pulls up next to you.
The TV is always four boxes. Nobody in a box? It's the highlight cam, the last place cam (the announcer goes after them, and their mother), or the helicopter.
A D steer, F grab, G item, H hose, R wipers, T horn. Arrows + J K L U I.
