I would just install a 200 amp service. The difference in material costs is minimal between a 200 amp and a 150 amp and the amount of labor is the same.

I don’t understand the power lines capacity. From the utility. How many amps are in those utility conductors???

It doesn’t really matter. If they need to be upgraded they will upgrade them.

Just a regular electric car. A grocery grabber.

We stopped using the chart in 2014.

150 AMP breaker X 83% = 124.5 AMPS. #1 is 130 AMPS, so #1 is OK.

Overhead/underground? Call them first. Explain what you are doing. While the NEC applies to you they are the ones supplying the power. They may have certain rules in your area
