I understand the sentiment, but I disagree. In the UK at least, it was the norm for years to install guardrailing in the place you describe. But, it became clear that it encouraged drivers to go faster and also, if there was an incident with a cyclist, the latter would be pinned against the railing and the outcome would be worse. It depends on the situation obviously, but loads of railing has come out and is installed much less frequently in new situations.

Damn, that’s an eye opener. Never crossed my mind before reading this.
