Explanation:

okay so i just wanted to know if anyone actually reads the paragraph explanations or not so this is my test if you red this comment "cow" if no then well don't but yeah all I'm really just doing this as experiment so if you are still reading say (cow as I said before) but that's really it the answer is correct but still

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

is this a question? wassup
