Unless your car is a Kei car, which is one of the main reasons those exist. IIRC.

As far as I’m aware, the big issue is the parking minimums at businesses, not residential buildings. I.e. what you call point B, rather than point A. That’s what basically forces huge unwalkable strip malls. Which forces them out of the city. Which forces people to always drive there.

Now, the numbers in Nashville do seem a bit high. But the alternative to built-in parking spots in residential buildings is street parking, which costs just as much as built-in parking, but is entirely paid for by taxes instead. Street parking also takes up space that could be used for protected bike lanes.

AH and PH do form a right angle, that’s postulated in the problem. But P is only the projection of H onto the plane if PH is indeed parallel to n. Which is not necessary.

Imagine a nail patrols hammered into a piece of wood at an angle. The wood surface is the plane, the entry point is H and the head of the nail is P. A is anywhere on the line perpendicular to the nail on the board.

If you shine a light from above, you can see P’, the projection of P as the end of the shadow cast by thaw nail. Unless the nail is straight, P’ != H.

Putting some numbers (for the US) here, from a recent Forbes article

Joining the top 1% requires a net worth of $11.6 million to $13.7 million

Surely it’ll get better now that modal filters across residential streets were declared illegal.
