Light trucks is kinda a crazy category. It's lighter vehicles that
(1) Designed primarily for purposes of transportation of property or is a derivation of such a vehicle, or (2) Designed primarily for transportation of persons and has a capacity of more than 12 persons, or (3) Available with special features enabling off-street or off-highway operation and use
Vans, minivans, SUVs, and crossovers are mostly categorized as light trucks. Most vehicles on the road are light trucks; they outsell cars right now 3 to 1
Somewhere like the Netherlands, every bike racer is going to have at least two bikes: a regular commuting 'granny bike', and a racing roadbike.
Just as it's common for a runner to have regular-ass shoes for going grocery shopping and a pair of running shoes they only really use when training for a marathon, or for reasonably well-off car/ motorcycle enthusiasts to have a more practical regular car they use for daily driving and a less practical sporty vehicle for pleasure drives.
Road bikes like you see in the Tour de France aren't really a practical form of transportation. You have special shoes that clip to the pedals, you wear lycra bike shorts, etc.
