This is an awesome comment. It's like a mechanic saying Chevy's are a nightmare under the hood. The percentage of people buying cars that give a fuck is rapidly approaching zero because they never even see it.
Expanding on your analogy, the issue is when you need to start using your free car to safely haul lots of freight across the country in a timely manner, over multiple routes all while providing sound, reliable fleet maintenance with a team of mechanics. Some auto shops will tell you that duct-taping your freight to the roof of your car is just fine, others will tell you that you cannot run a reliable network with this system.
