because there are no more speeding cars and reckless drivers
Except there won't be and most likely there is a good chance there will be more reckless drivers as they get frustrated at being caught behind cars driving the speed limit.
Years ago Virginia wanted to raise the cost of their speeding tickets to around $1,000 but only if the person was caught going 20 miles over the posted speed limit. People were howling about how awful it was, how it wasn't fair and couldn't the state just raise their taxes so they could continue to speed.
See
this article for some comments, particularly this one:
"It's outrageous," says traffic court attorney Thaddeus Furlong of Springfield, Va. "When Mr. and Mrs. Middle Class find out what they have to pay, there's going to be a backlash like you've never seen."
something that makes the world better instead of being a necessary evil.
It's only a necessary evil because, to throw words back in people's faces, people refuse to live in a civilized society and not do things which endanger other people's lives such as speeding, talking on their cell phones while speeding, stiff-arming the steering wheel while speeding and talking on their cell phones, robbing, raping, and murdering people, to name just a few things.
