Your dilema is that ( in the UK ) pavements are for pedestrians and unless the local authority has clearly marked the pavement with lines & signs showing that it can be 'shared'; with pedestrians it is illegal to cycle on them. Pedestrians are as much afraid of the silent and often unseen cyclist as cyclist claim to be of motorists.
Also many highway authorities have a deliberate policy of narrowing road widths with frequent bollards etc as a means of slowing the motoring traffic's speed down, they may not admit it but part of the highway authorities strategy is to use narrow cycle lanes on the road with you, the cyclist, as a moving traffic obstruction so as to force car drivers to slow down behind you, this is partly why cyclists are on the receiving end of car drivers frustration and resentment.
Next point, there is no legal obligation upon cyclists to take out compulsory insurance but you are still liable to be sued for any accident or damage you cause.
It is still a legal requirement to have correct lights although you wouldn't think so from the number of cyclists that assume motorist have the eyesight of an owl and will spot you in the darkness without them. Surveys have show a high % of drivers actually drive below the legal eye sight limits !
It is also seems to be a little know fact that if you cycle on the road in the correct fashion red traffic lights also apply to cyclists and it is also an offence if, when you come to red lights, you dismount and push your cycle to avoid the lights and then jump back on !
Although all these legal rules are not in themselves arrestable offences the Police have a 'catch all' power of arrest for virtually any offence if they do not know and can not reasonably identify the offender or be satisfied that the normal method of taking down your particulars and reporting you will be effective.
Finally if you do decide to cycle good luck but could I persuade you not to ride with a jacket flapping in the wind, you could get caught and pulled of your bike by passing traffic and, like the truck drivers say to following cars, if you cant see the vehicle drivers mirrors the chances are he can't see you. Safe cycling.
