A. No one is prohibited from driving. TSA has the power to prohibit citizens from flying.

B. There is actual evidence to support the safety benefits of speed limits. There is no evidence that TSA procedures result in significantly improved safety.

C. To restrict a citizen's rights, you must prove that it is crucial to do so and that the restriction will be minimized. TSA has yet to justify its existence (e.g., by providing independently verified cost-benefit analyses supporting TSA procedures), so there is no proof that TSA's power to prohibit flying is crucial to national security. Given that TSA indiscriminately requires (or has required) citizens' to turn over cupcakes, bottled water, and other innocuous items in order to fly, TSA's restrictions on citizens' right to travel by air are hardly minimized.
