People of the average income level spend less on petrol when getting more cash, from 5% of the lowest budget in this level to 4% of the highest one. The figure sharply decreases to 2.3% when people become the richest US citizens.

The figure continues to rise to 3,8% when people approach the next level. For the richest individuals, they keep their spending at 3,8% and slightly decrease it by 0,5% at the time they become the richest ones.
