As has been mentioned above, each chaser has their own agenda and style of chasing, and in the main, that's fine. When it's not fine is when the agenda is purely to get amazing footage to sell on, with scant regard for anyone else, shouting and screaming into the mic as they roar after the tornado. Sure, we all get excited, and occasionally scared by severe weather, but in my book, that doesn't mean you have to scream your lungs out for the benefit of the watching audience.
Back in 2001, whilst positioning ahead of the southern supercell on May 29th (TX P'handle, near Tulia), we pulled over to watch the developing storm. Quite a few other chasers were there, including several van loads of what appeared to be university chase teams. One of these teams thought it would be best to put on their music as loud as possible, and several others were making a darn racket. Now I don't mind high spirits, etc, but in the right place at the right time. At the side of a quiet Texas road, near some farmsteads, with a developing supercell to the west is not the time in my book. Not to mention the fact that the first distant rumbles of thunder from a developing storm are priceless, in my mind.
Needless to say we quickly moved a bit further west to an altogether quieter spot.
I often pause before writing/commenting on storm chasing in the US, as I only come across there as a tourist, and as such, sometimes feel I shouldn't really be preaching to the residents. However, as a storm chaser, whether I'm in the US, or back here in the UK, I don't want to be labelled as some kind of nutjob that goes zooming off into the middle of any severe thunderstorm I can find. I'm a meteorologist, and I'm observing, documenting and learning about the most amazing weather on the planet, and I don't see why others should put that into jeapody.
