Imagine you owned a store, what seems better, having 40 customers come in and all of them buy or having 80 people come in and all use up time with a salesman and then only 45 people purchase. You would end up spending a much more significant amount of the sales revenue on the larger showroom and more staff. This isn’t my opinion this is why the American market has been prioritized, that and the fact that Americans spend more on cars per year
California has different emissions requirements (not safety) but since they are a strict upgrade to the rest of the US (and comparable to other int markets) as long as you follow their requirements all cars in the US can be sold without any contradictory requirements
A very common kpi used is to examine the success of a campaign in a per target demographic so having the much lower response rate is worse
Well this is a waste of my time so I will leave you with one final look up. How many cars are sold per year in the US compared to Europe?
Hint the answer is the US
