The number of models should match the number of DB Tables (minus the pivot tables)

Yes models play big role, for example if you have a repeated code in controllers for a specific model why not move it into model. I hope you can understand where I am coming from any data implementation or structuring should go into model. You don't have to put everything into controller.

I don't see any difference between using a model to do

 Vehicle::where('ID', '=', '1')->first();

and just using this

 DB::table('vehicles')->where('ID', '=', '1')->first();

All that models do is connect to databases? Are they more secure than DB::table?

Maybe not much difference for that query but to me, the model version looks cleaner

Vehicle::with('colour')->whereHas('price', function($query)
{
	$query->where('amount', '<=', '10000');
})->where('active', 1)->get();
