He says 35k km over 3 years so nearly 12,000km per year. He claims gas is $360 per year. That would get you about 5,000km in a small car like he describes. He’s obviously understated the gas cost, probably by leaving out the larger than normal costs when taking the longer trips to the beach/wife’s family. $30 (400km) of usage a month driving to the shops/short trips sounds about right.
