This guide aims to help players defend themselves against attackers by disable their means of transportation (player vehicle) in Red Dead Online.
Efficient Method to Destroy Player Vehicles
Please, Be Mindful
Use in self defense, against people who attack you.
Important: the costs of protecting yourself.
Important: Killing a player horse or any vehicle (except Npc Mission wagons and Moonshine wagons) even in self defense will result in 4.00 Dollars fee so if you want to actively use this tactic you have to spend your cash before going in free roam. I usually stock up on ammo, dynamite, and try to buy items that I want like clothes or upgrades if I have a lot of money to bring it down and not waste it. Because if you kill many horses it is a considerable sum. 10 horses is going to cost you 40 dollars and if you kill a 100 it will be $400.
Keep your money below $4 and it will never be used but you can spend it on fast travel if you need it and I suggest you always keep some animal parts, flowers, collectibles and jewelry as bank for when you need a larger sum of money for more fast travels or a small purchase so you can exchange it with a butcher/doctor/madam nazar, or a fence.
Horses are the mains means of transportation. Disabling them is easy.
You can use a shotgun with standard ammo to get a 1 hit kill from up close or a sniper rifle with express ammo for 1 hit kill from distance. You can only buy express ammo from a vendor. To disable a player for a longer period of time so he cannot use a horse longer only wound the animal but never finish it. It will add extra 30 seconds on top of 2 minute re-spawn timer.
You can also use dynamite to kill horse but it can be tricky if they are on the move so you have to time it right.
Using fire bottles is not recommended.
Wagons, Trader Wagons, Hunter Wagons
If a player is riding a wagon, or doing a wagon npc mission, or doing a trader mission, or collecting hunting supplies and decides to attack you whether for fun or in fear of you shooting first there is a way for you to stop the player from following you, and or attacking you by disabling the vehicle.
For this to be effective you need to either have dynamite (or dynamite arrow) and blow up the wagon which will render it useless and thus unable to follow (destroying its wheels). Dynamite can be bought in a max stack of 8 at a fence $1 each or during a showdown mission
You can also use explosive ammunition which can be crafted with a pamphlet which can be purchased for $1000 from a fence using animal fat from animals like bison, bear, duck, goose, boar and others combined with express bullets (1 fat per 1 express bullet). To disable a cart/wagon you need to shoot it in the wheel, or to be more specific in the center of it, at the disc that attaches it to the shaft (image included below).
You can also try using incendiary slugs (can also be bought at fence butt work less efficiently than fire bottles) for shotgun or fire cocktails but those seem to work from time to time as 1st the wagon needs to catch fire and then spread to the wheel.
As a side note, you can of course also try going for the horses but wagon horses seem to be the most damage withstanding horses so it may sometimes be hard
Tip: you can also buy a stronger dynamite recipe pamphlet from fence "volatile dynamite" and dynamite arrow from any fence
Sometimes even Moonshiners get spooked or overconfident when they come across players, much like in the section above and you will also need to find a way to disable them. All the same tricks work on the moonshiner's wagon, however, it seems that it has reinforced back wheels (Larger wheels), I shot 6 explosive rounds into them and they wouldn't go off. So the trick with moonshiners is to destroy the front wheels to disable the wagon.
Sometimes a wagon will still function without a single wheel so you will need to destroy both front wheels or both back wheels or both side wheels for it to stop functioning. A cue that it has stopped will be horses unhitching from wagons and running off
Another valid strategy is to attack the moonshine bottles from behind the wagon as it will either make the owner switch his priorities and stop chasing you or will whole together disable the wagon. They can be destroyed with any ammo type.
