There is no need to go that high in salary (a lucky very small minority). The higher income tax band (40%) kicks in at 50k. Salary sacrifice schemes offer huge savings to many people.
What I mean is that if salary sacrifice schemes on EV were only used, and very good deals, for people over 100k then it would be extremely niche as we're talking about the top 4% of earners whereas about 16% are higher band taxpayers...
People on higher salaries are disproportionately likely to be the ones doing it though - much much more likely to work for companies that implement the schemes for a start.
Yes, "higher salaries" as in higher tax band (median salary is 39k, higher tax band starts at 50k), which impacts 16% of people. That's why it has an notable impact on sales and also on the used cars market (salary sacrifice schemes are usually PCP/leasing over 3-4 years).
Perhaps it is the "London bubble" on HN as I feel that no-one is registering that 100k+ is a really, really small minority...
