AJ & McCall: Lawnmower Test Drive Debate @8

An argument started during a VFX Facebook Roulette about lawnmowers. AJ thinks you should absolutely be able to test drive them while McCall thinks that’s ridiculous. She has bought a nice lawnmower recently and even has stats. AJ thinks you should be able to test more things, but not everything. What is something used you would never want for the Debate At 8?
