When you start getting into high dollar and highly organized teams, it just feels nice. The shop I was in was kind of a mess. Like a crazy scientist kind of mess. The owner was the Doc Brown of 2 stroke engines and so I was the one keeping the sanity of the place. We worked closely with an Indycar team and when I walked into their shop it was amazing.
Everything is much simpler than expected. The specialized tools for the cars are not that complex, just tailored and simplified for the task. Everyone has everything they need, but only what they need. Sorted, organized, high quality and dependable setups. Lots of light, and cleaner than my fridge.
My shop was high quality but trying different things and tackling many mini projects so it was all over the place, but our engines were damn fast and we had some rule bending tricks to stand out. Both seem very fun.
Many of the pit mechanics at Indy races are there for free. So many people want to work there that why even offer money
I hung around in a pit while I was in college, just an extra hand helping my friend's dad who competes in drag races. That was a super interesting experience, but a lot of unsafe, messy (arguable illegal) shit going on. Being an Asian in an all "country boy" environment wasn't pleasant, but I enjoyed my team's company. I can't even imagine how freaking cool it would be to work on F1 teams.
