Adjustment to tax

I believe taxes should be adjusted to promote purchases of new cars and multiple cars. Taxes right now are as follows (as far as I am aware)
Houses:
.5%- >300k

1%- <300k
Cars:
1%- >300k
2%- <300k

Solution 1
I think the way the system is currently discourages people from owning multiple cars but encourages people owning multiple houses. I think this is backwards and these two asset taxes should be switched. I completely understand why taxes exist to encourage player engagement and economy control, but I believe with a tax structure for cars that is lower it will encourage more people to own more cars.

Owning an expensive mansion is a privilege and you are likely to only have one and we should encourage people to only own one as there is limited real estate. This would help fix the real estate problem as well as there assets will cost more to maintain.

Solution 2
There are other solutions such as reducing the high end rate. As many of us know the cars we actually want are around 300-500k. Maybe cars should have a asset tax range more in line with the current economy so it would be 1% for everything below 500k and 2% for everything above 500k which is another solution
