Yes, aerodynamics are much better, and computer modeling helped. Things
have been fine-tuned to the point that a Tesla can get 3.4% more efficiency
out of merely using the stock "aero" wheel covers rather than something
"prettier". (I know this because back in 2019, people had these things
called "parties", and talk turned to Telsas, as everyone wants to at least
appear to reduce some of their massive carbon footprint.)1
But, I still drive my 1952 MG TD when weather permits, and it has not just
the aerodynamics of a brick, but a vertical-slab radiator shaped like a
brick. Anyone who drives an older car in the USA is still seeing far less
insects on windshields, despite the impressive plantings of wildflowers by
state departments of transportation on medians and roadsides.
As my Dad says before nearly every rally we run - "Son, in this life, you
can be the windshield, or be the bug."
