The people who advocate for an engine freeze crack me up...it's even worse that you advocate for such a thing on a site named F1Technical. They're also the same mouthbreathers who whine about the lack of technological development in F1.
Newsflash: You can't have it both ways. If you want mostly bunched up fields, then you need to watch spec-series racing. If you want to see F1 as a true technological breeding ground --no matter if the tech makes it to everyday world applications-- then you cannot have the series exist as a combination spec-series conducted on low grip tires. Guess what, if you want technical development, then you are going to have to get back to not penalizing on the limit driving, and accept that fields will spread out.
It's a total sham that was never a part of what F1 was about.
F1 was very much about in-season development, as it was what made F1 such a unique race series. The clock on development never ran out. From Brazil to Adelaide in another era, it was all about trying to improve design as long as you had the cash. It also was a hell of a lot more interesting in those days, as the news wasn't a constant circle jerk of rumors and innuendo because nothing else goes on.
