I can't say this applies, but one factor that increases the number of unsafe drivers on the road is this nation's abysmal mass transit infrastructure. Unless you live in a major city you pretty much have to own a car to get anywhere or do anything.
And even then, traveling from city to city can also be impossible.
Where I live all mass transit shuts down on Sunday, most also on Saturday. No train service, and the bus runs only once an hour, on weekdays, and only until 9 pm, and only to a very small number of locations. And I live in a area that has above average service for a town this size.
It's pathetic, how dependent we are on cars. The way we structure our transportation means people who can't drive are under virtual house arrest (especially if you use a wheelchair or walker). Not to mention: it's destroying the climate all around us, contributes to the continued existence of regimes like those in Saudi Arabia and Russia, distorts our foreign policy, and pumps billions and trillions of dollars into the pockets of right wing oligarchs--which is probably why it won't change until it's too late to save what's left of our environment.
Also: I HATE car ads. All this bullshit equating cars with "freedom" and "power" and sex appeal, when in fact for most people they simply suck up time and money that could be spent living more rewarding lives.
One final note: they enable said right wing oligarchs to manipulate the economy so as to toss elections to the right. Case in point: blaming President Biden for high gas prices.
One final final note: tens of thousands of dead people each and every year.
