Five quantities, one at a time -- how heavy, how many, how far. You reason out loud to a number and the passenger types it in any form you say it: 3m, 3 million, 3000000. You are scored on how many TIMES off you were rather than by how much, so being within double beats being within tenfold whether the answer is in the hundreds or the quadrillions. The round is cleared if your average over the five stays inside the level's factor. Nothing here is recall; every figure can be reasoned toward.

Players: Two or more people in the car.

Driver: Thinks out loud. Nothing to memorize.

The bar: How many times off you may be on average. Tightens every level.
