How would you estimate the number of registered commercial trucks in DE?
Tried to approach the question by estimating the number of supermarkets (~30,000) and the number of trucks needed to replenish them every day (1-2 truck loads required per day), which make me come up with 60,000 trucks - I assumed that the replenishment of supermarkets account for only 10% of the overall delivery demand, but even so I only arrive at 600,000 trucks, which is one fifth of the overall official number (official estimate: 3 Mio.).
Can anyone help me out here?
Thanks a lot in advance.
