i just want 2 imagine if have accident how man... just my advise to all using smart tunnel.. don speed inside... bcoz out tires wont have full potential grip with simen... and when inside a tunnel our car aerodynamic don help... no wind pass through... its all stuck under the tunnel.. so don take fast corner in tunnel.... if any accident.. sure gone 1 .
Yeah i agree with u bro.
Sigh its so uneven it gives me a headache. Too bumpy for me. :X-:
