And still explains why four wheel drive causes less vehicle control. You had to release hubs because ‘always on’ four wheel drive decreases safety when moving. Obviously.

Either each wheel operates independently. And then tires do not fight each other. And then one tire that slips is the only wheel turning. So, four wheel drives interconnect all wheels so that all spin together. So that no one wheel spins with other not spinning. Wheels must be interconnected to that all wheels turn even when one slips.

All wheels interconnected means tires fight each other. But then anyone who knows before posting also knows that four wheel drive means tires fight each other - diminished control. But that is not in myths promoted by advertising.

Yes, four wheel drive means better traction when starting, as I said repeatedly and you agree. Because no wheel can be permitted to spin independent of others. That same interconnection makes the vehicle more hazardous when moving. Tires now fight each other when any one must spin more than any other.

Also correctly noted is the advantage of front wheel drive. Put numbers to it. Front wheel drive means 60+% of body weight on the traction wheels. Any increase to 100% has diminishing returns. Four wheel drive is 100% traction on the drive wheels. So that vehicle can get started. Percentage of body weight on traction wheels is why 60 to 100% is preferred. And why pick-up trucks have poor traction. (Pickup trucks must be filled in back to have traction.)

When stopping, only front wheels do most all braking - for all vehicles - two wheel and four wheel drive. On ice, the driver must decide whether to steer or brake. More braking means less steering. Same for both types - two or four wheel drive.

So that one wheel does not do all spinning, a four wheel drive must 'tie' all wheels together. That means a moving four wheel drive has less traction due to wheels fighting each other. That means front wheels must steer, brake, and fight all other tires for control.

Four wheel drive only to get started. And to have less control when moving. But you cannot tell that to an ego who is sitting higher than everyone else. Advertising told him he is invincible. And both angry and insulting when reality is posted.
