Tbh no that good place for afternoon?im there when the time is 5pm,and I wrote the sign for Bristol or Exeter, a lot cars pass by there but not stopping (it’s but hard)but luckily a lady pick me to the half way in Swindon,and I got another car after 30mins come to Bristol.its maybe a good place for morning hitchhiking,it was Sunday

don't know if I was lucky, but I got a lift all the way to near Swindon (could've gone to Heathrow!). they've got plenty of time to size you up coming out of the petrol station but put Bristol or M4 to cast the biggest net if you're going that way. I tried once using this spot for heading north, which is much much harder to do

Medium petrol station, decent spot to get out of London. I got a lorry to Swindon early morning.
