text: The cost of making these cars and testing them will cost so much money and if the cars dont work and experiments with them dont work it will be drastic. Alot of people will be paying for these experiments with there taxes ands thats not fair for people that work hard for there money to just through it away on the invention. This would also be a big problem in are money and state money because if it doesnt work and they wasted all that money are state could possible become in debt. All this money put into will be a waste and companys will probably be shut down and that will be the end of it for them.
