Seems you can vote one time everey day !!!! I tried 3 days ago after voting the day before and to day again ? seems vote number have changed second after ??????? is it that possible

it's me or am missing something
Could be the reason why that "weird car" have so many votes and Brian beeing so far ?????
I checked also to day to do a second vote! immediatly after the first ; this time the site gave the message " you already vote " so there is already a safety barrier ?????
have not read all rules ..... may be there is an article on rules explaining that stuff ???
Could some one try ????? and report
