It’s pretty obvious that cars are getting bigger and bigger. What has not gotten larger in commensurate are the width of roads, and the size of home garages. The former is easy enough to fix: just tear up the current lane markings, and replace with ones wider apart. Obviously, certain streets are going to be impossible to do. For those situations, I think you simply have to ban cars of a certain size. Much like how some residential neighborhoods prohibit 18-wheeler trucks from entering.
Parking lots are similar to roads. The lot at my workplace have already gone through a widening of the berths. Previously, it had gotten so bad that you cannot open your own driver door if the car to your immediate left did not park exactly in the middle of two lines. You know who’s got the best parking lot? IKEA. The berths there are so wide - to accommodate furniture loading - that even the largest of SUVs has no issues fitting in comfortably.
Logic would say that if cars continues to get bigger, it’s only a matter of time before the parking structure at work will need to have its lines repainted again.
Cars becoming too wide to fit home garages is a far more difficult fix. Some of the older homes I see in San Francisco, ones built way back in the previous century, have garage openings that appears incapable of allowing a modern SUV to pass through. No wonder people would rather park on the street and use their garage space as storage! Widening a garage aperture is going to cost many thousands of dollars, and applying for a few permits. As we know, permits in San Francisco are super easy to get, so long as you know who to bribe.
One of the items to check off when buying a house should absolutely be: can your car fit in the garage with room to spare? Or maybe this is only a San Francisco problem. Everything is bigger in Texas, am I right?
