Back to you. First, I don’t believe you did that 4 wheeling in your MY so it’s not relevant. I used to too. Second how do YOU secure large items in you ModelY? Don’t spout safety issues, just answer the specific question. Or quit knocking those who can’t figure it out. And try to stay off your soapbox while answering, you’re not the only one who likes to do thinks safely, I have a long history in the aviation industry. Not reckless.To actively disagree and say it's dumb to secure cargo "because everyone does it" is laughable. But you do you. Never said otherwise.
*and you can disagree and feel it's fine to not be concerned. Absolutely your choice. The topic should be weighed, so that people can make that choice.
