Clearly, to many, for example those involved in motorsports and touring, cars are more than mere means of transport.Well,I agree to what you had to say.
Car is a means of transport and should be treated so. But then i have seen people who travel more than 120Kms every day, for example Abu dhabi-Dubai route.
For such people car becomes a place in which they spend close to 2-3 hours in a day.
Under such circumstances, people do tend to get attached to the non-living thing in which they spend so much time. Plus luxury and its safety features get a lot more importance.
So in my view— doing car reviews is not a bad thing.
