I think it is important to say for people who maybe dont fully understand how an LSD works (probably the majority of drivers), that in normal everyday driving it will make precisely zero noticeable difference.
When driving in say a spirited manner on public roads it will certainly have an advantage over the same model of car that is not fitted with one.
It is also true that when driving on slippery surfaces and maybe not being fully respectful with the controls it will have a positive effect...basically saving you from yourself.
An LSD is not some kind of magic thing that will instantly make a bad driver better, but it will enable a competent driver to make more use of their cars performance potential.
There is a certain kudos about being able to say your car has an LSD, but If you just want to drive your car 'normally' then it should not be an important consideration.
I have only ever has one car with a factory fitted LSD...it was a highly performance orientated model but I only drove normally at a fraction of its potential, so the fact that it had an LSD made no difference to me.
We are all different in what we want from our cars and how we want to drive them, so the fact that these options exist is a good thing IMO.
