Just make the punishment for cheating sufficiently harsh. You cheat.. you get kicked out. Simple.
Most universities kick students out as soon as they are caught cheating. If the cheaters try to go to apply to another school, the last question on the app is usually "Have you ever been disciplined for Academic Dishonesty?", to which answering "yes" is an auto-fail.
I really hope we get this electric car thing figured out soon because I am just about sick of following smoke belching vehicles every day.
The electrical components of my gas burning vehicle shorted and caused the rest of the vehicle to be consumed by flames in a very smokey manner, certainly smokier than other car I've observed. As the electric parts of the car were responsible for said fire, it seems resonable that electric cars will burst into flames more often than gas burning cars. Therefore, it can be logically deduced that electric cars will result in much more smoke than the fossil fueled alternatives.
Life is a healthy respect for mother nature laced with greed.
