Buuxi weedha soo socota: Jonathan Martin, madaxa BBC Sport, wuxuu sii haystay adeegyada Walker ee shirkadda ee BTCC ka dib markii qandaraaskii dambe ee rullaluistemadka la soo gabagabeeyay bishii May 1997. Walker wuxuu doortay inuusan cusbooneysiin qandaraaskiisa BBC-da 1998 si uu diiradda u saaro baahinta ITV ee Formula One mana uusan dooneynin inuu si joogto ah ugu safro London si uu u duubto faallooyinka BTCC. Waxaa jiray dhowr Grand Prix intii u dhaxeysay 1978 iyo 1996 oo Walker uusan faallo ka bixin intii uu u shaqeynayay BBC, badanaa taas oo ka dhalatay faallooyinkiisa meelo kale. Qaar ka mid ah kuwan waxaa ka mid ahaa 1979 Belgian Grand Prix iyo 1988 Hungarian Grand Prix (markii Simon Taylor uu u beddelay), Jarmalka Grand Prix ee 1981 iyo 1984 (labadaba waxaa faallo ka bixiyay Barrie Gill), iyo
1985 Tartanka Jarmalka ee Grand Prix (Tony Jardine).
