I don´t think they need to add DRS zones to tracks with a lot of straits. It is already really difficult to leave the DRS window in Italy. They rather should add DRS zones in tracs like Monaco where it is nearly impossible to stay in DRS range.
I'm for a greater similarity to reality. I offer my vision. perhaps where it is more difficult to implement, perhaps there are other suggestions. in Monaco, you can put the DRS zone in the tunnel
