Some years of the new Fiat 500 have a secret compartment under the passenger seat cushion. I checked, and mine (2016) doesn’t. Darn it.
My BMW 330GT is 2014 and it has lane departure warning. It won’t autosteer (except when parking) but it will vibrate the steering wheel if it sees you over 70kph crossing the lane markings if visible.
it’s one of my pet peeves with Tesla FSD and Autopilot that sometimes it sees the lane widening for an off ramp or left turn lane and try to split the difference, thinking the lane is simply getting wider and it should stay in the middle. Updates in the last year have fixed this to a decent extent and it knows where the real lane is - usually. it would only try to steer you wrong (so to speak) if you have Autopilot or FSD engaged. Smart cruise control leaves steering up to me.
This is tangential, but is absolutely true. When I was in college, two of my friends had modified their cars so the windshield washer tubing came down and ended underneath the dash. They then filled the washer bottle with whiskey. This allowed them to hold a glass, paper cup of soda, or whatever just below the dash and pump whiskey into it by pushing the windshield washer button. (They did spend some time cleaning out the bottle and the tubing first.) Their rationale was that there would be no observable liquor bottles or containers in the car. Their cars were very popular at beach parties and concerts.
That’s funny. Ingenuity used for nefarious purposes. Along those lines, a friend had a car that he drag raced occasionally, mostly at the drag strip but sometimes on the street. He wanted it to be fast, but look stock. The engine appeared to be the stock 6.3 liter v8, but was actually an 8.3 L with numerous internal modifications. He had oversized mufflers to keep the noise down.
In the interest of reducing weight, parts had been removed, but not where you would see it. For example, some the of the steel structural braces, etc, had been replaced with ones he’d fabricated from aluminum, then painted the stock color, and welded back into the car. You’d never know, looking at them. The car was 400 pounds lighter as a result but you couldn’t see where the weight was cut.
The high compression engine required a huge and heavy battery to start it. To aid traction, he relocated the battery to the trunk. Back then, if you saw such a modification, it would tell you the car was serious; so he hid it. Up front, the battery cables were attached to the posts of an empty shell of a battery. From there, he ran cables under the car to the trunk, where the cables came up to the real battery, which was covered by a plastic tool box with no bottom.
All his mods and tuning made it a deceptively quick car. A stock one would accelerate through the 1/4 mile in about 15 seconds, about like a 4 cyl Camry nowadays. His would run the quarter in the 11s, or as fast as a Ferrari or Mclaren.
