But Siddh, they normally do it only once a week and that too on late Friday nights is what I have observed. Is there any harm in it? The traffic moves more slowly for say 10-15 mins but come on, it is not office time.

Rather than a 'vulgar display of wealth' I feel it is their way of relaxing on a weekend. As long as they don't harm anybody I feel its o.k. They are just having a nice time.

Well, I wish to join the convoy sometime just for fun...:)

Everything gonna be alright!!!
