I'm tired of suggesting that will not be the case, yet you keep banging the same message.
One last time: visa exempt entry via air is already unlimited.
However folk using a few/many back to back are being scrutinized and on occasion even refused entry.
This was widespread in particular in 2019 just prior to covid.
The same thing will most likely occur with land borders.
Also there is nothing to suggest this increase to 60 days will be permanent.
