i do not like planes but prices of ryanair are very cool and make travelling affordable .
cars are a good idea.... but the people managing the market are not
they are always making bigger motors , bigger cars....
i would prefer to live on earth like it was at the da vinci or even " Julius Cesar " than what it is now...
beside the cars there are too much roads , highways...that take a lot lot lot of space...
that is bad that they never made 2 ways-railways and make cars allowed to use them...no needs of google'cars with rails ..no accident and less energy needed .
the other big advantage is the low impact on the land and living population...and the air being fresh with odors of nature...
with train may be riding horses/elephant could still be possible ?
fires are a big problem , they kill trees and turn land into deserts..
the main bad thing is the latency , i am sure that in Portugal , they do like here : only little houses with little gardens...so that destroy the nature with no place to go ...while some buildings could reduce costs of every thing and make some structures like hospital possible at very low price ..keeping the space for sports or agriculture or even hunting ...
one thing seems sure , the global warming is slow , but going back with temps seems even more slower ...
our era is like the meteorite that punched earth and made a climate change...impact itself took minutes...the time when all was back to normal took million years
