This submission has been removed because it violates our '20-Year Rule'. To discourage off-topic discussions of current events, questions, answers and all other comments must be confined to events that happened 20 years ago or more.

As I read your question, you aren't asking so much for an explanation of what 'The Grand Tour' entailed, or what the experience was like, but for people to come up with that activities are the modern equivalent, which would violate the sub rules. If you are looking for the former though, I would suggest re-posting and making that more clear.
