An iPad costs a couple hundred bucks, and is tiny. A Tesla Roadster costs tens of thousands, requires a full-time employee to babysit it during a test-drive, has to be insured, and fills a room.

You're not comparing apples to oranges. You're comparing a paper airplane to a 747.

Not to mention that most Apple devices can't harm anyone else - i.e. there is no third-party liability that Apple may have to assume (or buy insurance to cover) if you (a free 'test driver') harms someone else with their test product.

This $300 is definitely not unreasonable.
