This thread is great, since it's all over the map. I'll give my ten most hated places:
The light outisde my house, 64th @ Lyon Rd. in Delta. (Excessive Speeders + Hidden solid red light = very dangerous, bad enforcement, and really scary)
Hwy 99 EB merge from WB Hwy 10 in Delta. (100 km/h speed on 99, but give absolutely no merge lane to get to speed. Those rare Semi drivers that use it, boggles the mind)
Fraser Hwy EB after 168th, 2 lanes to 1 in Surrey. (Right lane merges very quickly, a concrete barrier instead of a gradual merge)
Oak St SB after 70th in Van. (Weavers, enough said)
Knight St NB & SB at 33rd in Van. (no left turn lane/weavers)
Hwy 10 EB @ Scott Rd. (back up to turn left in pm. rush./blind corner)
King George SB after 32nd Av Diver in South Surrey. (useless 2 lane section, too short, and people cut you off)
64th EB after 176th in Cloverdale. (2 lane merge, but people use it mostly to cheat, it ends too quickly, always fun not letting someone in though)
Pattulo Bridge NB & SB (SB weavers before Royal, NB timid drivers are half that mess)
Nordel Way through Delta both ways (EB has no left turn lanes yet at Brooke and Sheppard. Always fun driving along really quick than seeing that f***er put that signal on. WB people tailgate really bad going down that hill. They put radar at the bottom, seems like a pretty smart thing since it's a 60 and people drive over 100 down. But today for example I'm going down at 85 to head SB 91, and a driver flips in behind me and starts basically touching my bumper... I'm pretty sure 25 over is an expensive ticket, you want me to go faster than that. Nope I'll just check my brakes a few times and slow to 60, and it's your fault. )
