Car features I don't understand - educate me

I don’t understand the purpose of a tachometer in an automatic. Well, maybe a sporty car, but what’s the point in an econobox?

My last car had a g-force gauge. Kind of hidden in the menu. Completely useless

I live 4 houses from a street-end intersection. When I start my Subaru and back out of my (not long suburban) drive, I shift into drive. When heading towards the street end, the screen is off well before I hit the intersection. Mild irritant, but awfully mild.

Back in the mid 90s I drove a friend to the airport, we took their car, a Honda Accord. I drove it back to their house, got out, and tried to push down the driver door lock. I pushed harder. I pounded on it, swearing. Then his mom came out of the house and was like WTF are you doing to my car?

You could only lock the driver’s door (when it was open) by putting the key into the lock on the driver’s door and turning it. It was lockout prevention in the era before remote keyless entry was ubiquitous and $500 replacement keyfobs were a thing.

Not if it kept a record of the highest values. “Look, here’s where I did 0.9 in a turn! And here’s where I did 12g when I hit the oak tree!”

Reminds me of the times when we glued 3 dollar replacement keys somewhere on the underside of the car… Just in case…

My first car was a 1990 Honda CRX (a two door hatchback), and it had a similar feature. The work around was that you could lock the door if you first lifted up on the door handle. It became habit for me to lock my door this way as soon exited my car. That stopped when I once managed to lock myself out of my own car while the keys were still In the ignition and it was running.
