It seems to change drastically every decade or two for me:
In the 70s I’d either get a lift from my Mom, or my drummer would haul everything in his gigantic Buick station wagon.
In the 80s and 90s I drove compact cars with a hatchback that, if you folded the back seat down, could easily accommodate all my gear. Plus maybe one bandmate. (In the mid-80s I also briefly owned a 1964 Chevy Greenbriar van, which could easily haul the entire band’s gear, but that van was a flaming POS so I went back to compact hatchbacks.)
In the 00s and 10s I lived in New York City, so I mostly used the MTA subway to get to gigs, 95% of which had venue-provided backline. For the few that didn’t, either a bandmate with a car, a taxi, an Uber, or, in a couple instances, the aforementioned subway…while carrying a pair of lightweight speaker cabinets, a Class D head, and my bass! Not recommended
And now in the 20s I’m driving an enormous Honda Pilot SUV which is so huge I have to strap the seatbelts around my cabinets to keep them from sliding around.
