The dangers of that web site are much more subtle and hard to defend against than those associated with "a motor vehicle", by which I guess you mean something like a car.

You can see traffic. It's easy to understand the dangers in a collision because when you drive into something unexpectedly your body takes a hit and you get frightened since you immediately realise that it might cost you a lot of money but you don't know for sure.

Being subtly manipulated by a disgustingly subservient fake conversationalist is another thing altogether.
