I have mentioned some of the reasons in an edit to my above reply, but to partially restate: All actions have unintended consequences on unconsenting passersby.

I have mentioned some of the reasons in an edit to my above reply, but to partially restate: All actions have unintended consequences on unconsenting passersby. To some, it is inconceivable to, if it can be avoided, get behind the wheel of an automobile when doing so actively increases the danger and probability of collision and injury. You are blind if you do not see this in your own life, or if you fail to see that the privileged life that you do enjoy is only possible because of the tragic conditions of life and strenuous labor that the rest of the world endures for your pleasure. Owners of older cars work hard or spend a great deal of money to maintain their vehicles in good operating condition, but the machines have quirks, some of which are impossible or not worth solving. That does not make them unsafe. That does not make them oblivious endangerers of the unconsenting co-users of the roadway. You have one notion of what it means to be a safe driver, others have different ones. Should people be allowed to drive 5000lb luxury barges, an unregulated and unpermissioned doubling of the amount of force at play in any collision that has been forced upon pedestrians and cyclists and drivers by motorists’ unquenchable thirst for increasingly sedate, massive, and insulated driving experiences, where visibility is almost 0, and drivers are completely dependent on the onboard sensors and warning lights to indicate to them whether or not switching lanes will end someone else’s life
