Golf sized EV is ideal for Europe, Golf and smaller are mainstream, normal. Many people won't buy a Model 3 or bigger car. It's too big to be desirable as it's not practical.
That's blocking out most of a large market (roughly 15 million comapred to 17 million in the USA but cars/vehicle definitions vary).
Model 3 and larger can only address a niche even if really cheap.
"current UK
norm for parking spaces is 2.4
metres wide by 4.8
metres" - various sources
Note that that is a 'norm', not a minimum, there are plenty of smaller spaces. These are designed spaces, not the kind you get in crowded streets where one car parks between two others. Sometimes there isn't room to step between vehicles when you cross the street. In these circumstances, having a long car means you really struggle to park on your own street, while short cars find it much easier.

Model 3 is 4,694 mm L x 1,849 mm W x 1,443 mm H
Width gap: 2.4m - 1.85m is

Length gap: 0.1m is
39 inches
Other countries can have far less space in cities.

"Each vehicle in Tesla’s lineup displaces a gas vehicle that burns more carbon than the gas hatchbacks displaced by EV hatchbacks." - Polo/Golf/smaller hatchbacks do long distances. They are usually people's only car, often just one per family. They are chosen in preference due to their size, economy and other attributes. They are used on family holidays to UK, Ireland and mainland Europe and on long commutes.
What is normal in North America is not normal elsewhere. When
locals are saying smaller Teslas are required in their markets, I urge you to keep an open mind.
