You Should Know
YSK - for all the things that can make your life easier!
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with YSK.
All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.
Rule 2- Your post body text must include the reason "Why" YSK:
**In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content. **
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-YSK posts.
Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you harass or discriminate against any individual member, you will be removed.
If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- The majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.
Rule 11- Posts must actually be true: Disiniformation, trolling, and being misleading will not be tolerated. Repeated or egregious attempts will earn you a ban. This also applies to filing reports: If you continually file false reports YOU WILL BE BANNED! We can see who reports what, and shenanigans will not be tolerated. We are not here to ban people who said something you don't like.
If you file a report, include what specific rule is being violated and how.

Huge heavy SUVs and large trucks absolutely do cause wear and tear, and EVs are especially heavy. The surface layers of roads are damaged over time by vehicles if the foundation of the road mostly remains unimpacted.
The weight of a heavy electric Hummer is 4.5 metric tonnes.
The maximum allowed weight of a fully loaded cargo truck is 44 metric tonnes.
According to the fourth power law, this would make the impact of the truck more than 500 000 that of the Hummer.
https://en.wikipedia.org/wiki/Fourth_power_law
Sure, the Hummer itself is already 16 times worse than a regular 1 ton car, but in the scale of things, the difference between any personal vehicle and a truck is about the same as whatever the truck is.
The fourth power law applies to weight per axle, assuming identical axles/tires. In reality, the typical tandem axle arrangement on big trucks (18 wheels across 5 axles, the four back axles paired together as tandems) spreads the load over a much larger road surface area than a typical 4-wheel passenger vehicle.
Also, the models themselves aren't that robust. It's from a single comprehensive study of loaded trucks, from 1958-1960, that has been very influential, but the tests itself never went down to passenger car weight.
Civil engineers have models and formulas for that, and there is indeed much more road deformation from the heavy trucks, but it's probably closer to thousands of times the load for an 18-wheel tractor trailer than for a passenger vehicle, not 500,000. Note in that analysis, it talks about which power to use (not always 4) for different types of road wear or damage, and many of them are less sensitive or more sensitive to vehicle load.
It's all interesting stuff, but I worry that people on the internet have put way too much value on the fourth power law here, stretching it beyond the original scope or overstating its applicability to practical road design issues.
While big cars do more damage than small cars or a bike. It's seriously negligable compared to any sort of goods transport vehicle
