Because the information necessary for that is already available from the subnet mask WITHOUT the bitwise AND, e.g., with 255.255.255.0 or 1111 1111.1111 1111.1111 1111.0000 0000, you count the amount of 1s, which in this case is 24 and corresponds to that appendix in the CIDR notation. At this point, you already know that you only need to consider those first 24 bits from the IP address, making the subsequent bitwise AND redundant.

On a technical level, the bitwise operation is all that is needed. It is one calculation of the simplest kind. A CPU can do it in 1 tick. That's why they invented it this way.

The other way that you described is the super extra ultra lengthy complicated - and maybe redundant - thing.

but would it not be easier to

Seriously?

All the world is doing it for decades, and we never thought of asking you how to do it right?

;-)

No weapons, just you and the squirrels.

My teeth are terrifying weapons, chrrrr!!

😄

In a fight to death, my only problem would be that I get tired from the fighting, sooner or later. And then they could do some real harm.

On the other hand, I assume that they are not smart enough to apply any special tactics that make use of this, or of their large number (coordinated action etc.)

So I would trust myself against maybe 50 of them.

The outside is the easy part (unless there is thick ice): use the water spray with the wipers. In the winter, the water contains a thawing solvent.

For the inside, what I personally do in the winter: before parking my car in the evening, I open all the windows for a few minutes to let the cold air in (also switch off the heating). Cold air is very dry. So it does not mist up (most times) in the morning.

I hit a barn with a dump truck because the clutch pedal failed to disengage the clutch

Then your right foot was not firmly on the brake, see step 1.

I guess they just don't use broken cars in the driving test.

I definitely agree that

I recommend to make yourself familiar with the concept of some things being true even if you don't agree to them.

There are even things that still remain after nobody believes in them anymore (that is one definition of 'reality').

I guess countries are not made for your expectations...

What are you supoosed to do if you want to let the car warm up

LOL

Guess what: You are supposed not to do it.

That is explicitly forbidden in Germany, for the sake of the environment.

The sad news is:

Their argument could fall on fertile ground.

The Usamerican legal system protects a running business. When such a rich and famous corporation argues (and it would be highly paid lawyers arguing) that their business could be in jeopardy, they are going to listen, no matter how ridiculous the reasoning.

In other countries, they just make a judge laughing out loud.

No. If the clutch is in, there is no need to put in neutral. (You would not pass the driving test in Germany)

The correct steps are:

Right foot press down on the brake

Left foot press down on the clutch

Start the engine

Release the hand brake

Check that the 1. gear is in

Then release the brake, get on the gas just a little, release the clutch carefully, and there you go.
