This much hyped new system of transport has had a lot of coverage. It's never out of the news.

So, just how practical is it ? How safe is it ?

If SpaceX and Tesla are investing in it, it can't exactly be a gimmick but there are so many holes being picked in this, like the extrordinary power requirements for creating, even a partial vacuum.
Without the vacuum, we just have a tube. The likes of which we've had since the mid 19th century.

More hype than hyper.
