With the difference that the dryer connections are usually installed when the house is built so there's easy access to run the wires to and from the breaker box. Installing them afterwards is more expensive and complicated to do because of the limited access.
It's also not something you can expect to find anywhere other than at another EV owner's place. Admittedly over time that will become less of an issue but for now it's going to be pretty rare.
No for existing construction they will be more complex because the walls are all closed in so routing the 220V cable to the outside or garage is more difficult. Electrical is done before the walls are finished for a reason...
Maybe not if you're lucky and the existing dryer connection is already in your garage but it's not going to be that simple for most people. Again dryer connections get installed at build time and have for the last couple decades so most people already have them.
I'm an opponent of EV, but bring a cable from power input to garage is really not a big problem. Done that for many things over the last 20 years, including network cabling for internet access.
