Thank you! Great videos! there is not much content on vehicle physics, please keep up the great work!

[skmp]

its SO amazing how I can combine this and your "Making a Drift Game, Drifting Score" video. Goodjob I'm a big fan of this series!

Man, I've been following your tutorials for a while now and so far I think you're the only one that produces both advanced and easy to understand tutorials for beginners, with consistency. You DEFINITELY deserve more than just <10k views average. You help me a ton!

Also, maybe you can do a tutorial for a garage system in the future, where you can buy and equip various cars. And maybe even a basic color customization system too.

Mate I just want to say your videos are excellent and have helped me so much. Thank you

Great job, may I ask what version of Unity Editor you are using?

[VsevolodPankratov]

Thank you! You have a great realistic car controller! It would be helpful if you added nitro acceleration and police pursuit.

what about open world city traffic? i have to place waypoints everywhere?

[MorninCupofHate]

why not use atan2 for the steer angle? the ai would get a much more precise steering capability.

Are you available for small freelance projects

[eliezeralisson]

Great video, I'm having trouble simulating engine and transmission for my car system

[dhinakaran]

Would be cool if you could implement a multiplayer feature as well But great video.

theres simpler way to get childs without main object, you could just write
foreach (Transform child in transform)
{
waypoints.Add(child);
}
