The logical solution when this is the case: Drive less, and that's exactly what a decent portion of American drivers are doing.Source: LendingTreeSource: LendingTreeAdvertisementAdvertisementLendingTree, the online financial platform, polled 1,603 U.S. drivers this past July and compiled the info for us to look at. With the national average price of a gallon of regular-grade gas cresting the $4 mark, it's coming up on a dollar more per gallon than this time last year. This isn't breaking news to anybody, but it still hurts our wallets.Diving into the study, we learn that a surprising 34% of drivers are in fact driving more than this time last year. But that's massively encompassed by 81% of the respondents saying they have changed their driving habits and driving-based tendencies (errands, hunting for cheaper gas stations, avoiding some trips altogether, etc.) due to the cost of gas.Meanwhile, 10% of the polled population is spending over $1,000 per month on transportation costs, while 30% are spending less than $100. 26% are in the $100-249 range, 20% in the $250-499 bracket, and finally 14% of those polled spend $500-999 on their monthly transportation costs. Though this data is a bit of a misnomer, as CarScoops notes that only 68% of the people who responded to the poll actually have regular access to a vehicle and drive said vehicle regularly.Source: LendingTreeSource: LendingTreeAdvertisementAdvertisementThe consequence of higher gas prices is multi-fold, with drivers using their vehicles less than they otherwise would. The high prices could also steer some buyers into EVs, avoiding the cost of fuel altogether (we know it's more complicated than this, but for the sake of the gas prices argument, EVs are exempt).Again, none of this is a huge surprise. When so much of the US population lives either paycheck-to-paycheck or is substantially impacted by their available income associated with involuntary costs that they have effectively no impact on determining (i.e., the cost of a gallon of gas paired with commuting needs), the fat has to be trimmed off the top somewhere. As it turns out, that means less driving for many, and if gas prices continue to rise then it will only get worse from here.
