So a boattail must provide drag reduction and higher speed benefits that counteract its additional length and mass

So far, the boattail on my car hasn't been a detriment in parking or in traffic and I've been driving with it on my car for 2 years.
Hmmm. Interesting about parking/traffic.

Squid go tentacle-forward, gathered into a fairing shape, though octupi have tentacles trailing, also in streamlined configuration. Both are jet propelled, as opposed to wagging their tails like normal fish and dolphins, as I understand it.

BTW, have you tested your car with vs. without the front end mods, but with rear end mods, to see how much the front fairing helps?
