Linking and intrusive /r/

Linking /r/, retained historical post-vocalic word-final /r/ occurring before a vowel in the following word, is, as stated above at lettER, a normal feature of Received Pronunciation. In the most careful, mannered forms this might be avoided, rendering far away  rather than  : it is unlikely that many speakers feel under special pressure to avoid such an hiatus now.

The insertion of a non-historical intrusive /r/, referred to in commA above, when following word-final before a word beginning with a vowel, has typically been proscribed for users of Received Pronunciation. This creates an hiatus between the adjacent vowel sounds or, alternatively, a glottal plosive might be interposed between them, giving  l aw and order. RP shows no such inhibitions, with intrusive /r/ being the norm:  the idea of it. Similarly, intrusive /r/ occurs as the RP norm word-internally where the need is to avoid the hiatus, thus  drawing.
