It seems like the Lifeguard Post has very little value. There are only few possible missions (3 I think) that can be activated by building lifeguard posts, they don't count towards the number of stations needed to build additional coastal rescue heliports (1 heliport per 6 coastal rescue stations) and the vehicles are very similar to the Coastal Rescue Station.
To activate a lot of the possible coastal missions you need quite a few coastal rescue stations (up to 20) so why not focus on building coastal rescue stations and forget lifeguard posts? I get the Lifeguard post is only 50,000 vs 500,000 for the coastal rescue station, but spending even 50,000 on a Lifeguard Post seems like a waste when you should focus on building coastal rescue stations to activate new missions and unlock more coastal rescue heliports.
So what is really the point of using Lifeguard Posts? Just realism? I am trying to figure out if I am completely overlooking the value in a lifeguard post.
Maybe after building 20 coastal rescue stations and opening all the coastal missions, lifeguard posts might make more sense to get more vehicle coverage?
I am curious about other people's opinions who have built out a lot of coastal things.
