Let's see and challenge some principles of TRIZ in America.

Most of the car park in America has only concrete block on the left side to stop the car , no need to block both sides of the front tires.  They can save cost quite a lot through out the country.

This is really using the Principle of Asymmetry.

Most of the public car park in America are arranged in the open-air area.

Developers of shopping malls don't invest in car park building or installing roofs to prevent heat for the cars of their customers.

It is deadly hot here during July August and September, hotter than the Songkarn Festival in Thailand, more than 40 degree celcius.  Your car is really on oven for cooking. The sun shield in the front glass seems not enough to protect your car from the heat.

Here is a big business chance.

Can anyone ideate some solutions to this problem ?

Try to use TRIZ approach.
