Squids, cuttlefish, and octopi are jet propelled and don't have tails. When moving fast, they combine their tentacles into the shape of a boattail rather than a Kammback. But if all else was equal, a Kammbacked tentacle package would be preferable from a predator avoidance standpoint, since it doesn't stick out as far as a boattailed tentacle package and would be harder for a pursuing predator to grab. 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.
