> (I don't even know whether you still have to manually check the level of oil? Don't they have sensors for that these days?) Most cars do have sensors for this, but they often fail, and even if they're working fine, tell you at a warning level, not at a full level. If you want to be a prepared driver you'd check your fluids regularly, but especially before long trips; The bonus is that the sensors can't tell you that your oil is prematurely dirty, so just by looking at it, you get more information. This reminds me of Obama recommending people check their tires; yes, modern vehicles have tpms, but if they heed the warning, it often doesn't come on until a tire is significantly low ~20%.

There are so many mechanics that will do free or low cost inspections for things like that, why wouldn’t I do that before going on a long trip? Speaking of which, that’s yet another thing we pay for other people to do. If it’s a trip longer than about five hours we are flying or if we are being cheap and it’s not too far (around 6 to 7 hours) and if possible, taking the MegaBus.

  Going to a mechanic to have your oil level and tire pressure checked sounds like you would spend more time driving than just doing it. Then there is the fact that about half those places specialize in making up stuff that is wrong with dumb peoples cars to rip them off.

    We also fly out of Atlanta - the world’s busiest airport - and live an hour or more away depending on traffic. The calculus between whether it’s worth the hassle to deal with going to the airport, driving, or taking MegaBus changes the calculus considering the ceremony of getting on the plane can take an additional 2-3 hours with travel, security, and getting there early.

  It would be great if everybody did this! Or even rental car companies.

Interesting. Do you know why the sensors seem to have a binary output only, as opposed to checking for full level and dirt? If we put our minds to it, these days we can often make sensors that are much better than humans for these kinds of applications. Btw, you are talking about the former US president Obama? Seems a bit weird for him to care about car maintenance?

    More topical was the fuel efficiency at the time https://www.politifact.com/truth-o-meter/statements/2008/aug/05/barack-obama/not-overinflated-though-it-sounds-like-it/ https://www.politifact.com/truth-o-meter/statements/2008/aug... Estimates were that 25% of American tires were underinflated, wasting 2.8 billion gallons of gasoline every year.

  It was during the 2008 campaigns with high fuel prices; He was ridiculed for the simplicity by the right, but the NHSTA estimated that 25% of American tires are under-inflated at a cost of 2.8 billion gallons of gasoline every year.
