I love this kinda thing and - if I had Sir Rod's bank account - would probably purchase some augmented reality goggles and bring the city alive with traffic, pedestrians and King Kong with bi-planes.
If I'm interpreting the second picture right, he may be one step ahead with traffic. It looks like each carriageway has a continuous slot, so I'm going to guess that traffic is on a very long loop, one for each direction so the traffic is constantly moving over that bridge.
Can't tell from what I can see of the city detail in the last photo if that's the same.
Maybe there's money in specialist toys like that. How much would Sir Rod Stewart pay if you built him that? Or maybe there isn't. After all, if it isn't exactly like what he'd like maybe he wouldn't pay.
