My LOI was 1dn, because I had a mental block. I liked 23ac for its disguise, and 19dn for its humour, but I might pick 24ac as clue of the day.
Clues are in blue, with definitions underlined. Answers are in BOLD CAPS, then wordplay. (ABC*) means ‘anagram of ABC’, with the anagram indicator in bold italics. Deletions are in [square brackets].

Down

This was hard to see, because in my ignorance of all things related to horses and carriages, I imagined a hansom cab with its roof and doors was a different, heavier class of vehicle than a gig, which I imagine as light and open. But the dictionary agrees with the setter that hansoms are light two-wheeled carriages.

Annoying. Phil Jordan
The HOG’S BACK I know is a section of the Guildford bypass that’s notoriously treacherous and was the scene of an accident in 1959 in which the first UK Formula One Champion Mike Hawthorn died.

I knew Lope de Vega from somewhere and constructed the unknown Podsnap.
But I failed to get 1a despite frequently driving along the Hog’s Back, normally en route to Farnham golf club. I also failed to get 1d despite seeing how the clue must work. Perhaps if Danny Dyer had been on Have I Got News For You a week earlier it would have helped.
Off to watch Blackheath play rugby today so I won’t be spending too long on today’s puzzle. Blackheath is considered to be the first rugby club in the world. David
