not true mate, last year though not reported on tv, 2 death's (separate incidents)due to racing!, blackwall tunnel is just as bad for accidents if not worse due to being so tight, not too sure about them being speed camera's though there primary use is traffic monitoring due to accidents increasing in frequency. Main problem with any of the under passes in london is volume of traffic and most are being fitted out with camera's now.oh just for you info bufty's ou there even thought the rotherhithe tunnel has a speed limit of 20MPH! it still has speed camera's which are used and is in the top 10 of europes most dangerous tunnel! i will check the info out today and post back on what i find.
