As the title says, I know that different shifts mean different gear sizes bein used, but I don’t understand why it makes you unable to start moving the car. I have been able to start a couple of cars on the 2nd shift as an experiment and I understand that I could damage the car and I do it just once for testing purposes but I don’t understand why I cannot do so on other shifts. To clarify, I mean start as in start moving the car and not just turning the car on. Thanks

Some cars do. For example, I have a manual pickup which has a very low 1st gear designed to get heavy trailers moving. Normally, you would just start in second.
Basically it all depends how your vehicle is geared. Gears are one way to give you mechanical advantage. Basically, you can trade speed for power and vice versa. When you need lots of power, you pick a slow gear. When you need to go fast, you pick a higher gear.
It takes a lot of power to get a vehicle up to speed, but much less power to keep it at speed. Hence, starting in a low gear and working up to a high gear.
You could just put a massive engine in your car that has enough power to do everything (like an EV), but for a gas car, that would be really heavy and waste a lot of fuel.
