Most students do have cars, and the ones that dont live close to campus out of need. If the bus system will really improve rents that can be collected and business that is generated why dont those guys pay for it and charge a fair.... because you cant make money off of it. Tax dollars would have to be pumped into it unless the KSU threw down some money. There is already a transport from the stadium and there a plenty of other current programs that are hurting for money worse than someone that cant ride a bike or find a place semi-close to campus. The city has other problems to worry about such as schools, roads, etc. rather than building a bus system.
Overall it would be "cool" to have a bus system and might bring us up closer to what some other schools have but lets be honest, chances are pretty slim. A 18 year old kid isnt going to choose a school based on buses or no buses, most live in dorms anyway.
